Person A decided to boil water of mass m0 to make hot water.
After 4 minutes and 30 seconds, the temperature of the hot water changed from T0 (the temperature before heating) to T1 (the temperature after 4 minutes and 30 seconds).
Assume the thermal efficiency is η0 and the specific heat of water is constant at cw.
Answer the following questions.
(1) Find the total amount of energy ( J ) used to heat the water.
(2) Find the average power consumption (work rate) ( W ) of the heating appliance used to heat the water.
Let A1 be the answer to Part (1) and A2 be the answer to Part (2). Calculate the value of A1+A2 and enter that natural number.
