Answer: KE = 25 J
Explanation: You must use the formula
KE = 1/2 m v²
to solve this problem.
KE = 1/2 (10 Kg) (5 m/s)
KE = 1/2 (50 kgm/s)
KE = 25 J
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that both charge particles will exert equal and opposite force on each other
so here the force on both the charges will be equal in magnitude
so we will have

here we have

now we have

Part b)
Now for the force between two charges we can say

now we have

now we have

Unclear/incomplete question. However, I inferred you need an explanation of the phenomenon of rainfall.
<u>Explanation</u>:
Basically, the phenomenon of rainfall follows a natural cycle called the water cycle. What we call <em>'rainfall'</em> occurs when water condensed (in liquid form) in the atmosphere is made to fall down on the ground as tiny droplets as a result of the forces of gravity.
<u>The water cycle makes rainfall possible:</u>
- First, water on the earth's surface is evaporated (or is absorbed into) the atmosphere.
- Next, it then condensed into liquid form; which later falls to the surface to the ground again. And the process continues.
According to Newton's third law of motion, "The single ball on the left will move as high as the ball on the right was dropped" is the expected result once the ball hits the ball closest to it.
Answer: Option A
<u>Explanation:</u>
Newton’s cradle is the best example for law of conservation of momentum. So that means that energy or momentum exhibited by a particle can be transferred to its nearer object with equal force. So in the given options the first option is correct. As when the right ball is dropped it will collide with its neighboring ball and transfer energy.
By this transferring of energy from one particle to another, it will reach the leftmost ball. But there will be no loss in the energy as the left ball will move as high position as the ball on the right was dropped from. So that means the energy is conserved in the cradle.
Answer:
5:00p.m
She is traveling 30 miles and moves 10 miles for each hour therefore 30/10=3
This means she cycled for 3 hours adding this to our time we then have 5p.m
