Heat question

A man is drilling an iron block of mass 2kg. The power of the electric drill is 2kW. suppose 55%of the power has been lost as beat and increase the temperature of the iron block. (a) Find the temperature rise of the iron block in one minute. (b)If water is dripping into the hole at a steady rate of 15gs^-1, find... show more A man is drilling an iron block of mass 2kg. The power of the electric drill is 2kW. suppose 55%of the power has been lost as beat and increase the temperature of the iron block.

(a) Find the temperature rise of the iron block in one minute.

(b)If water is dripping into the hole at a steady rate of 15gs^-1, find the temperature rise of the iron block in one minute

( give that the spectific heat capacity of the iron block is 370Jkg^-1K^-1 and the water is
4200Jkg^-1K^-1
