C. Acceleration
UD. None of the above

4.68227 °C

Explanation:

= Mass of object = 500 kg

= Mass of water = 25 kg

c = Specific heat of water at 20°C = 4186 J/kg°C

h = Height from which the object falls = 100 m

g = Acceleration due to gravity = 9.8 m/s²

The potential energy and heat will balance each other

The temperature change in the water is 4.68227 °C
