4. A 0.2 kg ball rotates at a constant speed of 3 m/s on the end of 1.2 m long string. What is the centripetal force exerted on the object? Round the magnitude of your answer to the nearest tenths place.

a

explanation:

because they are cartillidge

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

because growing process had stoped after 4-5 year

this would be about 43%
