A stunt woman falls into a net. Assume she experiences upward acceleration magnitude while touching the net. Thanks :)

Explanation:

Minimum force means that the force should be applied at a 90° angle from the wrench.

40.0Nm / (0.30m) = 133.33N.

The mimumum force is 133.33N.

Answer:

A

Explanation:

The gold used in the making of jewelry is usually not pure but a heterogeneous mixture of metals. Pure gold is quite soft and even though it may look better in appearance compared to those made using heterogeneous mixtures, it usually bends easily. Hence, in order to make the jewelry more durable, gold is usually mixed with other metals to form a heterogeneous mixture.

The correct option is A.

Answer:

The number of moles of the air is 4.464 x 10⁻⁴ mole

The number of molecules is  2.688 x 10²⁰ molecules

Explanation:

Given;

pressure of the air, P = 1 atm

volume of the air, V = 1 m³

temperature of the air, T = 0° C = 273 K

The number of moles of the air is calculated as;

PV = nRT

[tex]n = \frac{PV}{RT}[/tex]

where;

n is the number of moles

R is ideal gas constant = 8.2057m³atm/mol.k

[tex]n = \frac{1atm \ \times \ 1m^3}{(8.2057 \ m^3 atm/mol.K)(273 \ K)} = 4.464 \ \times 10^{-4} \ mol.[/tex]

The number of molecules is calculated as follows;

1 mole  ---------------------> 6.022 x 10²³ molecules

4.464 x 10⁻⁴ mole ----------> ?

= (4.464 x 10⁻⁴) (6.022 x 10²³ molecules)

= 2.688 x 10²⁰ molecules of air.

Answer:

Acceleration

Explanation:

The choice from the given option which is not a force is acceleration.

Acceleration is defined as the rate of change of velocity of a body with time;

   Acceleration  = [tex]\frac{change in velocity}{time}[/tex]  

Force is a pull or push on a body. The product of mass and acceleration is force.

Answer:

The specific latent heat of ice is approximately 341 J/g

The correct option is;

b) 341 J/g

Explanation:

The given parameters are;

The mass of ice the pupil adds to the water, m₁ = 37 g

The initial temperature of the ice, T₁ = 0°C

The mass of the water to which the ice is added, m₂ = 100 g

The initial temperature of the water, T₂₁ = 30°C

The final temperature of the water and the melted ice, T₂₂ = 0°C

The specific heat capacity of the water, c₂ = 4.2 J/(g·°C)

By the principle of conservation of energy, we have;

The heat gained by the ice = The heat lost by the water = ΔQ₂

Given that the ice is only melted with no change in temperature, we have;

The heat gained by the ice = The latent heat needed for melting the ice

ΔQ₂ = m₂ × c₂ × (T₂₂ - T₂₁) = 100 × 4.2 × (0 - 30) = -12,600 J

The heat gained by the ice = m₁ × [tex]L_f[/tex]

Where;

[tex]L_f[/tex] represents the specific latent heat of fusion of ice;

We have;

12,600 = 37 × [tex]L_f[/tex]

[tex]L_f[/tex] = 12,600/37 = 340.54 J/g ≈ 341 J/g

The specific latent heat of fusion of ice = [tex]L_f[/tex] ≈ 341 J/g.

a control group

Explanation:

In a scientific experiment such as the one above, there is an experimental group and a control group. The experimental group is the group that receives the treatment while the control group does not receive any treatment. The control group helps the researcher to observe if the treatment had any significant effect.

In this case, it will help Alan and Monica to determine if fertilizer X actually had an effect on the plant. Therefore, the pot with o grams of fertilizer in it is the control group.

Answer:

The OatMeal

Explanation:

Answer:

C.) The Oatmeal


Since the oatmeal is the hottest it will spread the other substances which will increase the temperature of the milk, spoon, and the surrounding air.

The oatmeal had the most thermal energy out of the four options; the milk was cool, the spoon was at room temperature and the surrounding air was also at room temperature. Therefore, the heat from the oatmeal will travel to those substances and change their thermal energy.

#TheWizzer

Answer:

Explain. yes it is possible because when the net force is zero and acceleration is zero. ... no, Neglecting air friction, the only force acting on this object is the force of gravity downward. There is no force of equal magnitude as the force of gravity acting in the opposite direction.

Kinetic energy = 29.912 J

Given

mass = 0.155 kg

vo=initial velocity = 31.4 m/s

h/d=30 m

Required

KE=kinetic energy

Solution

vt²=vo²-2ad⇒vt=final velocity

vt²=31.4²-2.10.30⇒g=10 m/s²

vt²=985.96-600

vt²=385.96 m/s

Kinetic  energy (KE)

Answer:

SA = 5900 sqcm

Explanation:

I am assuming you meant surface area since this is a three dimensional box.  This formula for surface area (SA) is SA = 2 (wl + hl + hw).  Once you have that would just have to plug the numbers in and calculate!

Answer:

The joule is the standard unit of energy in electronics and general scientific applications. One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second.

Hope it helps ^^

Answer:

P = m g v

Explanation:

Power is defined as the relationship between work and time

        P = W / t

The work is defined by the scalar product of the force and the displacement, in the case of a drop falling the vertical force and the displacement has the same direction, therefore the angle between them is zero and the cosines of zero is one (cos 0 = 1)

       W = F y

the gravitational force is proportional to the weight of the drop  (F = mg)

        W = mg y

we substitute

       P = m g y / t

the terminal velocity of the drop is constant

       P = m g v

Answer:

personality disorder

Explanation:

Certain family dynamics, such as abusive parenting, can increase the susceptibility of someone developing a(n) personality disorder.

A disorder is diagnosed when these personality traits are significantly “deviated” from others and are very inflexible, impairing a person's adaptation to everyday situations and causing distress and discomfort in their personal relationships and other areas of life.

Personality disorders are generally pervasive and persistent patterns of thinking, perceiving, reacting, and relating that cause significant distress or functional impairment.

Explanation:

Answer:Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes. Scientists used the Richter Scale for many years but now largely follow the “moment magnitude scale,” which the U.S. Geological Survey says is a more accurate measure of size.

Answer:

atomic 11

Explanation:

atomic 11 Na is metal

Answer:

I think it could be C.

hope it helps!

Answer: The size of the force varies inversely as the distance square between the two charges. Thus, if the distance between the two charges is doubled, the attraction or repulsion will become weaker and decrease to one-fourth of the original value. The size of the force shall be proportional to the value of each charge.

It's Z your welcome :)

Answer:

It is Z i believe.

Explanation:

Potential Energy = mass x gravity x height

W: 980 = (50)(9.8)(h)

X: 1029 = (35)(9.8)(h)

Y: 1519 = (62)(9.8)(h)

Z: 1176 = (24)(9.8)(h)

simplify:

W: 980 = 490h

X: 1029 = 343h

Y: 1519 = 607.6h

Z: 1176 = 235.2h

Divide from both sides of each equation:

W: (980/490) = h

X: (1029/343) = h

Y: (1519/607.6) = h

Z: (1176/235.2) = h

Simplify the left side:

W: 2 = h

X: 3 = h

Y: 2.5 = h

Z: 5=h
