A waterfall is 60 meters high. What is the temperature rise in Kelvins of the water from just before to just after it hits the rocks at the bottom of the falls, assuming negligible air resistance during the fall and that the water doesn't rebound but just splats onto the rock

Explanation:

If we consider that all the gravitational potential energy () gets transformed into thermal energy (), we then have:

which means:

Since the specific heat capacity of water is , we have:

(A difference in Kelvin is the same difference is Celsius).

in physics zero. in muscle fatigue could be high

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
