Question

The energy dissipated by the heater is E. When the time of operating the heater is doubled, the energy dissipated is a. doubled b. half c. remains same d. four times

Answer 1

Explanation: The answer to your question is option C - "The energy dissipated by the heater remains the same." This is because the amount of energy required to heat up an object depends on its mass and specific heat capacity, not on the time it takes to heat up. Therefore, doubling the time of operation does not affect the amount of energy that needs to be supplied to the heater.
