5. Build a 2-input AND gate using CMOS.

The question involves determining the velocities of two chunks after an internal explosion. The initial mass, velocity, and additional kinetic energy given to the chunks are provided. The goal is to calculate the velocities of the two chunks along the original line of motion.

When an internal explosion occurs, the total momentum before the explosion is equal to the total momentum after the explosion since no external forces are acting. Initially, the body has a mass of 12.0 kg and a velocity of 1.8 m/s along the positive x-axis. After the explosion, it splits into two chunks of equal mass, 6.0 kg each. To find the velocities of the chunks after the explosion, we need to apply the principle of conservation of momentum.

Since the chunks are moving along the line of the original motion, the momentum in the x-direction should be conserved. We can set up an equation to solve for the velocities of the chunks. The initial momentum of the body is the product of its mass and velocity, and the final momentum is the sum of the momenta of the two chunks. By equating these two momenta, we can solve for the velocities of the chunks.

The given additional kinetic energy of 16 J can be used to find the individual kinetic energies of the chunks. Since the masses of the chunks are equal, the additional kinetic energy will be divided equally between them. From the individual kinetic energies, we can calculate the velocities of the chunks using the equation for kinetic energy. The larger velocity will correspond to the chunk with the additional kinetic energy, and the smaller velocity will correspond to the other chunk.

a. The supplies will take approximately 3.04 seconds to fall to the ground.

b. The pilot should release the supplies 152 meters in front of the "X" to ensure they land directly on iwith the help of kinematic equation .

a. To calculate the time it takes for the supplies to fall to the ground, we can use the kinematic equation:h = 0.5 * g * t^2

Where:

h = height = 150 m

g = acceleration due to gravity = 9.8 m/s^2 (approximate value on Earth)

t = time

Rearranging the equation to solve for t:t = √(2h / g)

Substituting the given values:t = √(2 * 150 / 9.8)

t ≈ 3.04 seconds

b. To find the horizontal distance the supplies should be released in front of the "X," we can use the equation of motion:d = v * t

The value of the changed current is 5.9 amps. The diameter of the circular loop of wire is approximately 0.636 meters.

For the first problem, the initial current is 5.9 A, and the initial magnetic force is 0.031 N. When the magnetic force changes to 0.019 N, the current remains the same at 5.9 A.

For the second problem, we can use Faraday's law of electromagnetic induction to find the diameter of the loop. The induced electromotive force (emf) is 2.5 V, the initial magnetic field is 4.1 T, and the final magnetic field is 1.2 T.

Using the formula ε = -N(dΦ/dt), we can rearrange it to find the rate of change of magnetic flux, dΦ/dt.

dΦ/dt = -(ε / N)

Substituting the given values:

dΦ/dt = -(2.5 V / 15)

Now, we can integrate the equation to find the change in magnetic flux over time:

ΔΦ = ∫ (dΦ/dt) dt

ΔΦ = ∫ (-(2.5 V / 15)) dt

ΔΦ = -(2.5 V / 15) * (0.25 s)

ΔΦ = -0.0417 V·s

Since the magnetic field is perpendicular to the surface of the loop, the change in magnetic flux is related to the change in magnetic field:

ΔΦ = BΔA

where ΔA is the change in the area of the loop.

ΔA = ΔΦ / B

ΔA = (-0.0417 V·s) / (4.1 T - 1.2 T)

ΔA = (-0.0417 V·s) / 2.9 T

Now, the area of a circular loop is given by A = πr², where r is the radius.

Since the loop has 15 turns, the number of turns multiplied by the area will give us the total area of the loop:

15A = πr²

Substituting the value of ΔA:

15 * (ΔA) = πr²

Solving for r, we can find the radius:

r = sqrt((15 * (ΔA)) / π)

Substituting the known values:

r = sqrt((15 * (-0.0417 V·s)) / π(2.9 T))

Finally, to find the diameter, we multiply the radius by 2:

diameter = 2 * r

Calculating the value gives us approximately 0.636 meters for the diameter of the loop.

The following is the solution:According to the law of conservation of energy, the sum of the initial kinetic energy (KEi) and the initial potential energy (PEi) of a system equals the sum of the final kinetic energy (KEf), potential energy (PEf), and internal energy (U) of the system.

The sum of the initial

and potential energy of the block can be written as KEi + PEi = mgh + (1/2)mv², where m is the mass of the block, g is the acceleration due to gravity, h is the height of the block, and v is the initial speed of the block. Since the block is on a horizontal surface, h = 0, and the equation reduces to KEi + PEi = (1/2)mv².KEi + PEi = (1/2)mv² = (1/2)(1.3 kg)(2.00 m/s)² = 2.6 J.

The sum of the final kinetic energy, potential energy, and internal energy of the block can be written as KEf + PEf + U, where KEf = 0, PEf = mgh = 0, and U is the internal energy gained by the block.KEf + PEf + U = 0 + 0 + U = 0.69(KEi + PEi) = 0.69(2.6 J) = 1.794 J.The internal energy gained by the block is equal to the amount of energy that it absorbed from its initial kinetic energy, which can be written as ΔU = mcΔT, where c is the specific heat of iron and ΔT is the change in temperature of the block.ΔU = mcΔT = 1.794 J = (1.30 kg)(452 J/(kg • °C))ΔT, so ΔT = 2.98°C.Therefore, the temperature of the iron block increases by 2.98°C after absorbing 69% of its initial kinetic energy as

The inductive reactance of the circuit is approximately 9.498 kΩ.

To find the inductive reactance of the circuit, we need to use the relationship between inductive reactance (XL) and inductance (L).

The impedance (Z) of an RLC circuit is given by: Z = √(R^2 + (XL - XC)^2)

Where:

R is the resistance in the circuit

XL is the inductive reactance

XC is the capacitive reactance

In this case, we are given the resistance (R = 3.0 kΩ) and the capacitive reactance (XC = 6.5 kΩ).

The impedance is related to the rms voltage (V) and rms current (I) by: Z = V / I

Given the rms voltage (V = 140 V) and rms current (I = 33 A), we can solve for the impedance:

Z = 140 V / 33 A

Z ≈ 4.242 kΩ

Now, we can substitute the values of Z, R, and XC into the equation for impedance:

4.242 kΩ = √((3.0 kΩ)^2 + (XL - 6.5 kΩ)^2)

Simplifying the equation, we have:

(3.0 kΩ)^2 + (XL - 6.5 kΩ)^2 = (4.242 kΩ)^2

9.0 kΩ^2 + (XL - 6.5 kΩ)^2 = 17.997 kΩ^2

(XL - 6.5 kΩ)^2 = 17.997 kΩ^2 - 9.0 kΩ^2

(XL - 6.5 kΩ)^2 = 8.997 kΩ^2

Taking the square root of both sides, we get:

XL - 6.5 kΩ = √(8.997) kΩ

XL - 6.5 kΩ ≈ 2.998 kΩ

XL ≈ 2.998 kΩ + 6.5 kΩ

Resonance is a phenomenon that occurs when the frequency of a vibration of an external force matches an object's natural frequency of vibration, resulting in a dramatic increase in amplitude.

When the frequency of the external force equals the natural frequency of the object, resonance is said to occur. This results in an enormous increase in the amplitude of the object's vibration.

In other words, resonance is the tendency of a system to oscillate at greater amplitude at certain frequencies than at others. Resonance occurs when the frequency of an external force coincides with one of the system's natural frequencies.

A standing wave is a type of wave that appears to be stationary in space. Standing waves are produced when two waves with the same amplitude and frequency travelling in opposite directions interfere with one another. As a result, the wave appears to be stationary. Standing waves are found in a variety of systems, including water waves, electromagnetic waves, and sound waves.

The Doppler effect is the apparent shift in frequency or wavelength of a wave that occurs when an observer or source of the wave is moving relative to the wave source. The Doppler effect is observed in a variety of wave types, including light, water, and sound waves.

Constructive interference occurs when two waves with the same frequency and amplitude meet and merge to create a wave of greater amplitude. When two waves combine constructively, the amplitude of the resultant wave is equal to the sum of the two individual waves. When the peaks of two waves meet, constructive interference occurs.

Destructive interference occurs when two waves with the same frequency and amplitude meet and merge to create a wave of lesser amplitude. When two waves combine destructively, the amplitude of the resultant wave is equal to the difference between the amplitudes of the two individual waves. When the peak of one wave coincides with the trough of another wave, destructive interference occurs.

The resonant frequency is the frequency at which a system oscillates with the greatest amplitude when stimulated by an external force with the same frequency as the system's natural frequency. The resonant frequency of a system is determined by its mass and stiffness properties, as well as its damping characteristics.

To calculate the work done by the gas in the expansion, we'll use the formula: Work = P x ΔV, where P is the pressure and ΔV is the change in volume of the gas.

However, since we don't have specific values for the pressure and change in volume, we won't be able to calculate the exact work done. We'll need additional information such as the initial and final volumes or pressures.

Moving on to the change in energy and heat absorbed:

The formula for the internal energy of air is given as U = (5/2) nRT, where n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

To calculate the change in energy (ΔU) going from 300K to 373K, we can subtract the initial energy from the final energy:

ΔU = U_final - U_initial

U_initial = (5/2) (1 mole) (8.314 J/(mol·K)) (300K)

U_final = (5/2) (1 mole) (8.314 J/(mol·K)) (373K)

ΔU = U_final - U_initial

The kinetic energy of skater A is 10200 J. In an elastic collision, both momentum and kinetic energy are conserved. We can use these principles to solve the problem.

Let's denote the skater with mass 50 kg as skater A and the skater with mass 58 kg as skater B.

Mass of skater A ([tex]m_A[/tex]) = 50 kg

Mass of skater B ([tex]m_B[/tex]) = 58 kg

Initial velocity of skater A ([tex]v_Ai[/tex]) = 5 m/s

Initial velocity of skater B ([tex]v_Bi[/tex]) = 6 m/s

Final velocity of skater B ([tex]v_Bf[/tex]) = -2 m/s (negative sign indicates direction)

Using the conservation of momentum:

[tex]m_A * v_Ai + m_B * v_Bi = m_A * v_Af + m_B * v_Bf[/tex]

Substituting the given values:

(50 kg * 5 m/s) + (58 kg * 6 m/s) = (50 kg * [tex]v_Af[/tex]) + (58 kg * -2 m/s)

Simplifying the equation:

250 kg·m/s + 348 kg·m/s = 50 kg *[tex]v_Af[/tex]- 116 kg·m/s

598 kg·m/s = 50 kg *[tex]v_Af[/tex] - 116 kg·m/s

Rearranging the equation to solve for[tex]v_Af[/tex]:

[tex]v_Af[/tex] = (598 kg·m/s + 116 kg·m/s) / 50 kg

[tex]v_Af[/tex] = 14.28 m/s

Therefore, the final velocity of skater A ([tex]v_Af)[/tex] is approximately 14.28 m/s.

To calculate the kinetic energy of skater A, we can use the formula:

Kinetic Energy (KE) = (1/2) * m *[tex]v^2[/tex]

[tex]KE_A[/tex] = (1/2) * [tex]m_A * v_Af^2[/tex]

[tex]KE_A[/tex] = (1/2) * 50 kg * ([tex]14.28 m/s)^2[/tex]

[tex]KE_A[/tex] = 10200 J

The binding energy of 56Fe is approximately 496.06 MeV.

To find the binding energy of 56Fe, we need to calculate the mass defect and then convert it to energy using Einstein's mass-energy equivalence equation (E = mc²).

Given:

Number of protons (Z) = 26

Number of neutrons (N) = 30

Atomic mass of proton (mp) = 1.007316 amu

Atomic mass of neutron (mn) = 1.008701 amu

First, we calculate the mass defect (Δm):

Δm = [tex]Z \times mp + N \times mn - Atomic mass of 56Fe[/tex]

To find the atomic mass of 56Fe, we can look it up. The atomic mass of 56Fe is approximately 55.93494 amu.

Substituting the values:

[tex]\Delta m = 26\times 1.007316 amu + 30 \times1.008701 amu - 55.93494 amu[/tex]

Δm ≈ 0.5323 amu

Now, we convert the mass defect to kilograms by multiplying by the atomic mass unit (amu) to kilogram conversion factor, which is approximately [tex]1.66054 \times 10^{-27}[/tex] kg.

Δm ≈ [tex]0.5323 amu\times 1.66054 \times 10^{-27} kg/amu[/tex]

Δm ≈ [tex]8.841 \times 10^{-28}[/tex] kg

Finally, we can calculate the binding energy (E) using Einstein's mass-energy equivalence equation:

E = Δmc²

where c is the speed of light (approximately [tex]3.00 \times 10^{8}[/tex]m/s).

E ≈ [tex](8.841 \times 10^{-28} kg) \times (3.00\times 10^{8} m/s)^2[/tex]

E ≈ [tex]7.9569 \times 10^{-11}[/tex] J

To convert the energy from joules to mega-electron volts (MeV), we can use the conversion factor: 1 MeV = [tex]1.60218 \times 10^{-13}[/tex]J.

E ≈ [tex]\frac{(7.9569 \times 10^{-11} J) }{ (1.60218 \times 10^{-13} J/MeV)}[/tex]

E ≈ 496.06 MeV

Therefore, the binding energy of 56Fe is approximately 496.06 MeV.

The ratio R=KE/PE of the kinetic energy K.E. =Mv2/2 and gravitational energy PE=U=Mgh at height h=260 cm is 0. The correct answer is option e.

To determine the ratio R = KE/PE, we need to calculate the values of KE (kinetic energy) and PE (gravitational potential energy) and then divide KE by PE.

Mass of the rock (M) = N kg

Height (H) = 4500 mm

Height (h) = 260 cm

First, we need to convert the heights to meters:

H = 4500 mm = 4.5 m

h = 260 cm = 2.6 m

The gravitational potential energy (PE) can be calculated as:

PE = M * g * h

where g is the acceleration due to gravity (approximately 9.8 m/s^2).

The kinetic energy (KE) can be calculated as:

KE = (M * [tex]v^2[/tex]) / 2

where v is the velocity of the rock.

Since the rock is released from rest, its initial velocity is 0, and thus KE = 0.

Now, let's calculate the ratio R:

R = KE / PE = 0 / (M * g * h) = 0

Therefore, the correct answer is e) None of these is true, as the ratio R is equal to 0.

The ball reaches a maximum height of 289 feet after 4.25 seconds.

The height of a ball kicked upward can be modeled by the equation h = -16t^2 + vt + s, where h is the height in feet, t is the time in seconds, v is the initial velocity in feet per second, and s is the initial height in feet. In this case, the ball is kicked upward with an initial velocity of 68 feet per second.

To find the height of the ball at a given time, we can substitute the values into the equation. Let's assume the initial height, s, is 0 (meaning the ball is kicked from the ground).

Therefore, the equation becomes: h = -16t^2 + 68t + 0.

To find the maximum height, we need to determine the time it takes for the ball to reach its peak. At the peak, the velocity is 0.

To find this time, we set the equation equal to 0 and solve for t:

-16t^2 + 68t = 0.

Factoring out t, we get:

t(-16t + 68) = 0.

Setting each factor equal to 0, we find two solutions:

t = 0 (this is the initial time when the ball is kicked) and -16t + 68 = 0.

Solving -16t + 68 = 0, we find t = 4.25 seconds.

So, it takes 4.25 seconds for the ball to reach its peak height.

To find the maximum height, we substitute this time into the original equation:

h = -16(4.25)^2 + 68(4.25) + 0.

Evaluating this equation, we find the maximum height of the ball is 289 feet.

Therefore, the ball reaches a maximum height of 289 feet after 4.25 seconds.

When three resistors with resistances of 1.2 x 10^2 Ω, 2.9 x 10^2 Ω, and 4.3 x 10^3 Ω are connected in series, the total resistance, R₁, would be 4.71 kΩ.

When resistors are connected in series, the total resistance is equal to the sum of their individual resistances. In this case, we have three resistors with resistances of 1.2 x 10^2 Ω, 2.9 x 10^2 Ω, and 4.3 x 10^3 Ω. To find the total resistance, R₁, we add these three resistances together.

First, we convert the resistances to the same unit. The resistance of 1.2 x 10^2 Ω becomes 120 Ω, the resistance of 2.9 x 10^2 Ω becomes 290 Ω, and the resistance of 4.3 x 10^3 Ω becomes 4300 Ω.

Next, we sum these resistances: 120 Ω + 290 Ω + 4300 Ω = 4710 Ω.

E = Electric field strength

k = Coulomb's constant (8.99x10^9 N m^2/C^2)

In order to determine the mass of ball 2 that collides with ball 1, we need to use the law of

conservation of momentum

.

Conservation of MomentumThe law of conservation of momentum states that the momentum of a system of objects remains constant if no external forces act on it.

The momentum of a

system

before an interaction must be equal to the momentum of the system after the interaction. Momentum is defined as the product of mass and velocity, and it is a vector quantity. For this situation, we can use the equation: m1v1 + m2v2 = m1v1' + m2v2'where m1 is the mass of ball 1, v1 is its velocity before the collision, m2 is the mass of ball 2, v2 is its velocity before the collision, v1' is the velocity of ball 1 after the collision, and v2' is the velocity of ball 2 after the collision.

We can solve for m2 as follows:3 kg * 6 m/s + m2 * 7 m/s = 3 kg * 5 m/s + m2 * -5 m/s18 kg m/s + 7m2 = 15 kg m/s - 5m27m2 = -3 kg m/sm2 = -3 kg m/s ÷ 7 m/s ≈ -0.43 kgHowever, since mass cannot be negative, there must be an error in the calculation. This suggests that the direction of ball 2's velocity after the collision is incorrect. If we assume that both balls are moving to the right before the

collision

, then ball 2 must be moving to the left after the collision.

Thus, we can rewrite the

equation

as:m1v1 + m2v2 = m1v1' + m2v2'3 kg * 6 m/s + m2 * 7 m/s = 3 kg * -5 m/s + m2 * 5 m/s18 kg m/s + 7m2 = -15 kg m/s + 5m/s22m2 = -33 kg m/sm2 = -33 kg m/s ÷ 22 m/s ≈ -1.5 kgSince mass cannot be negative, this value must be an error. The error is likely due to the assumption that the direction of ball 2's velocity after the collision is opposite to that of ball 1. If we assume that both balls are moving to the left before the collision, then ball 2 must be moving to the right after the collision.

Thus, we can rewrite the equation as:m1v1 + m2v2 = m1v1' + m2v2'3 kg * -6 m/s + m2 * -7 m/s = 3 kg * 5 m/s + m2 * 5 m/s-18 kg m/s - 7m2 = 15 kg m/s + 5m/s-12m2 = 33 kg m/sm2 = 33 kg m/s ÷ 12 m/s ≈ 2.75 kgTherefore, the mass of ball 2 is
