Answer:
The time is 133.5 sec.
Explanation:
Given that,
One side of cube = 10 cm
Intensity of electric field = 11 kV/m
Suppose How long will it take to raise the water temperature by 41°C Assume that the water has no heat loss during this time.
We need to calculate the rate of energy transfer from the beam to the cube
Using formula of rate of energy
Put the value into the formula
We need to calculate the amount of heat
Using formula of heat
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 133.5 sec.
