Ball bearings can be made by letting spherical drops of molten metal fall inside a tall tower - called a shot tower - and solidify as they fall. If a bearing needs 4.0 s to solidify enough for impact, how high must the tower be?

height of tower= 78.48 meters

Explanation:

So here are your givens:

time(t)= 4 s.

initial velocity(u) = 0 m/s

acceleration due to gravity (g)= 9.81 m/s^2

distance(s)=s meters

using one of Newton's equation of motion ;

height of the tower from the ground=total distance covered by bearing

height of tower= 78.48 meters

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
