At 5.0 minutes, the temperature of the water reaches 100 °C. The volume of the water in the urn is 3 000 cm and its density is 1.0 g/cm². The specific heat capacity of water is 4 200 J/(kg °C).
Calculate the thermal energy gained by the water.

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
