If a 10 kg body falls to the ground from a height of 15 m and if all its mechanical energy is convetred into heat the heat produced will be : (5 = 4.2 J/cal)

A

6 cal

B

60 cal

C

150 cal

D

350 cal

Text Solution

Verified by Experts

The correct Answer is:
d
Heat produced, `Q=W/J=(mgh)/(J)=(10xx9.8xx15)/(4.2)`
Q = 350 calories.
