Well its C, cant show you the work its in my head sorry.
Answer:
The four fundamental forces magnitude and range are in order of Strong Nuclear Force > electromagnetic force > weak nuclear force > gravitational force.
Explanation:
The 4 fundamental force are weak nuclear force, strong nuclear force, em force and the gravitational force are discussed below.
Strongest force is the strong nuclear force as compared to all of them. It is very useful for capturing the atoms nucleus together despite the large repulsion which is occur between the same charges due to protons in the nucleus.
Electromagnetic Force is the 2nd strongest fundamental force. Magnetism and electricity was thought to be of 2 separate forces.
Weak Nuclear Force involves the W and Z bosons exchange. It has a very short range of
Gravitational Force is the weakest between all the fundamental forces. However, due to its long range it is the most dominant force. It follows the inverse square law like but it is always attractive in nature.
Answer:
Explanation:
Given:
- un-stretched length of the spring,
- speed of revolution of the ball in horizontal plane,
- length stretch during the motion,
<u>Now the radius of revolution of the ball:</u>
<u>Now in this case the centrifugal force is equal to the spring force:</u>
where:
m = mass of the ball
k = spring constant
<u>Now the extension in the spring upon hanging the ball motionless:</u>
It helps in some way might want to researh some stuff before youdo it :)
