As the distance from the Sun increases the time to orbit the Sun increases. <em>(a)</em>
Examples:
-- Nearest planet to the sun: Mercury. Time to orbit the sun: 88 days
-- 3rd planet from the sun: Earth. Time to orbit the sun: 1 year
-- 5th planet from the sun: Jupiter. Time to orbit the sun: 12 years
-- 9th closest object to the sun: Pluto. Time to orbit the sun: 248 years
Another pair of examples:
-- Object in a near Earth orbit: International Space Station
Time to orbit the Earth: 90 minutes
-- Object in a far Earth orbit: the Moon
Time to orbit the Earth: 27.3 days
The reason for all of this is: Two things about orbits.
1). The larger the orbit is, the farther the object has to travel around it.
2). The farther out the object is, the slower it travels in its orbit.
This is simply the way gravity works.
Answer
Total force exerted by brake cylinders is 249.69 N
Explanation:
We have given that force ![F_1=38.7N](https://tex.z-dn.net/?f=F_1%3D38.7N)
And area of the cylinders ![A_1=7.61cm^2=7.61\times 10^{-4}m^2](https://tex.z-dn.net/?f=A_1%3D7.61cm%5E2%3D7.61%5Ctimes%2010%5E%7B-4%7Dm%5E2)
We have to find the total force
We have given total surface area ![A_2=49.1cm^2=49.1\times 10^{4}m^2](https://tex.z-dn.net/?f=A_2%3D49.1cm%5E2%3D49.1%5Ctimes%2010%5E%7B4%7Dm%5E2)
From pascal's law we know that ![P_1=P_2](https://tex.z-dn.net/?f=P_1%3DP_2)
And we know that ![P=\frac{F}{A}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BF%7D%7BA%7D)
So ![\frac{F_1}{A_1}=\frac{F_2}{A_2}](https://tex.z-dn.net/?f=%5Cfrac%7BF_1%7D%7BA_1%7D%3D%5Cfrac%7BF_2%7D%7BA_2%7D)
![\frac{38.7}{7.61\times 10^{-4}}=\frac{F_2}{49.1\times 10^{-4}}](https://tex.z-dn.net/?f=%5Cfrac%7B38.7%7D%7B7.61%5Ctimes%2010%5E%7B-4%7D%7D%3D%5Cfrac%7BF_2%7D%7B49.1%5Ctimes%2010%5E%7B-4%7D%7D)
![F_2=249.69N](https://tex.z-dn.net/?f=F_2%3D249.69N)

V/m is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 2.20 mT
<h3>Given the data in the question:</h3>
Magnetic field amplitude = Bm = 2.20 mT = 2*
T
Electric field amplitude = Em = ?
<h3>Electric field:</h3>
An electric field is a field created by electrically charged particles that attracts or repels other electrically charged particles surrounding it.
The greatest strength of the electric and magnetic fields is known as the electric field amplitude.
It can be said to be,
Em = c * Bm
Where, c is the speed of light(c = 3 *
m/s)
Bm is the magnetic field amplitude
On substituting the values we get,
Em = c * Bm
Em = 3 *
m/s * 2.20 *
T
Em = 660000 V/m
Em = 6.6 *
V/m

Answer:
the glove could be heavy so slowing down his power
Explanation:
JUST GUESSED
The ping pong ball was stopped because it lost its kinetic energy as it was made of plastic. The wooden ball gained the kinetic energy from the desk as it was also made out of wood.
That's my reasoning, Hope it is correct!
