find the ratio of the lengths of the two mathematical pendulums, if the ratio of periods is 1.5
Answer:
The ratio of lengths of the two mathematical pendulums is 9:4.
Explanation:
It is given that,
The ratio of periods of two pendulums is 1.5
Let the lengths be L₁ and L₂.
The time period of a simple pendulum is given by :
[tex]T=2\pi \sqrt{\dfrac{l}{g}}[/tex]
or
[tex]T^2=4\pi^2\dfrac{l}{g}\\\\l=\dfrac{T^2g}{4\pi^2}[/tex]
Where
l is length of the pendulum
[tex]l\propto T^2[/tex]
or
[tex]\dfrac{l_1}{l_2}=(\dfrac{T_1}{T_2})^2[/tex] ....(1)
ATQ,
[tex]\dfrac{T_1}{T_2}=1.5[/tex]
Put in equation (1)
[tex]\dfrac{l_1}{l_2}=(1.5)^2\\\\=\dfrac{9}{4}[/tex]
So, the ratio of lengths of the two mathematical pendulums is 9:4.

A. Have an equal number of charged and non charged particles.
B. Have neutrons in their nuclei.
C. Have an equal number of electrons and protons
D. Have an equal number of neutrons and protons
Atoms have no electric charge because they have an equal number of electrons and protons.
Explanation:
Atom is the smallest unit of matter.It is comprised of three subatomic particles: protons, electrons, and neutrons.Electrons are found outside the nucleus of an atom and are negatively charged.Protons are found inside the nucleus of an atom and are positively charged.Neutrons are found inside the nucleus of an atom and have no charge.They are electrically neutral because they have an equal number of protons and electrons.So from this, we can conclude that atoms have no electric charge because they have an equal number of electrons and protons. Option C is correct.

Two tougboats are toeing a ship each exerts a force of 6000N and the angle between the two ropes is 60 calculate the resultant force on the ship
Answer:
10392.30N
Explanation:
We proceed by computing the individual force exerted by the boats
For the first boat
The angle is 30 degree to the vertical
Hence
Force = F cos θ
F=6000 cos 30
F=6000*0.866
F=5196.15 N
Since the boats are two and also at the same angle and also exerting the same force
The Net force = 2*5196.15
Net force=10392.30N
The moon is significantly smaller than the sun. Why is the moon able to fully block the sun from our view on
Earth?
Answer:
The moon is 400x smaller but it's also 400x closer so it looks the same size even though it's not
Explanation:
To solve this we must be knowing each and every concept related to moon. Therefore, the moon is able to fully block the sun from our view on earth as it is 400 times.
What is moon?Any celestial object that revolves around a planet, such as the eight main planets, dwarf planets, or minor planets, is referred to as a moon. In order to distinguish the moon from other celestial bodies that circle other bodies, the term "natural satellite" may also be used to describe the moon.
The Galilean moons orbiting Jupiter, called after astronomer as well as discoverer Galileo Galilei, were the first moons found outside of the moon of Earth. The moon is significantly smaller than the sun. The moon is able to fully block the sun from our view on earth as the moon appears the same size despite the fact that it's 400 times smaller because it is 400 times closer and hence smaller.
Therefore, the moon is able to fully block the sun from our view on earth as it is 400 times.

You get a job delivering water. You calculate how much work is done picking up each 20 L bottle of
water and raising it vertically 1 m. For every 100 bottles you deliver, you will use Select.... (g =
9.8 m/s2)
-196J
-2,000 J
-19,600 J
-196,000J
Answer:
The work done by picking up 100 20-L bottles and raising it vertically 1 meter is 19614 joules.
Explanation:
By the Work-Energy Theorem, the work needed to raise vertically 100 bottles of water is equal to the gravitational potential energy, units for work and energy are in joules:
[tex]\Delta W = \Delta U_{g}[/tex] (1)
Where:
[tex]\Delta W[/tex] - Work.
[tex]\Delta U_{g}[/tex] - Gravitational potential energy.
The work is equal to the following formula:
[tex]\Delta W = n\cdot \rho \cdot V \cdot g \cdot \Delta h[/tex] (2)
Where:
[tex]n[/tex] - Number of bottles, dimensionless.
[tex]\rho[/tex] - Density of water, measured in kilograms per cubic meter.
[tex]V[/tex] - Volume, measured in cubic meters.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]\Delta h[/tex] - Vertical displacement, measured in meters.
If we know that [tex]n = 100[/tex], [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]V = 0.02\,m^{3}[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]\Delta h = 1\,m[/tex], then the work done is:
[tex]\Delta W = (100)\cdot \left(1000\,\frac{kg}{m^{3}} \right)\cdot (0.02\,m^{3})\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (1\,m)[/tex]
[tex]\Delta W = 19614\,J[/tex]
The work done by picking up 100 20-L bottles and raising it vertically 1 meter is 19614 joules.

A box slides down a ramp inclined at 24◦ to the horizontal with an acceleration of 1.7 m/s 2 . The acceleration of gravity is 9.8 m/s 2 . Determine the coefficient of kinetic friction between the box and the ramp.
Answer:
0.445Explanation:
In friction, the coefficient of friction formula is expressed as;
[tex]\mu = \frac{F_f}{R}[/tex]
Ff is the frictional force = Wsinθ
R is the reaction = Wcosθ
Substitute inti the equation;
[tex]\mu = \frac{Wsin \theta}{W cos\theta} \\\mu = \frac{sin \theta}{cos\theta} \\\mu = tan \theta[/tex]
Given
θ = 24°
[tex]\mu = tan 24^0\\\mu = 0.445\\[/tex]
Hence the coefficient of kinetic friction between the box and the ramp is 0.445

What is Newton’s universal law of gravitation?Newton's universal law of gravitation states that the force of attraction between any two bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.
Let the mass of the student be m.
Mass of the Earth = M.
Radius of the Earth = R,
So, gravitational force applied on the student on Earth surface :
GMm/R² = 500 N.
Again,
mass of the planet = 2M
Radius of the planet = 2R.
So, gravitational force applied on the student on the surface of the planet = G(2M)m/(2R)²
= 1/2 {GMm/R²
= 1/2 × 500 N
= 250 N.
Hence, His weight on that planet is about 250 N. option (D) is correct.

give the relation of resistance of wire with the length and thickness.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Give the relation of resistance of wire with the length and thickness:
Resistance:
There is a resistance to the flow of an electric current through most conductors.
The length of wire increases
The thickness of wire decreases
The resistance of a long wire is greater then the resistance of a short wire because electrons collide with more ions as they pass through.
The relationship between resistance and wire length is proportional. The resistance of thin wire is greater then the resistance of a thick wire because a thin wire has fewer electrons to carry the current.The relationship between resistance and the area of the cross section of wire is inversely proportional.
