Homework Statement
The Earth intercepts 1.27 x 10^17 W of radiant energy from the Sun. Suppose the Earth, of volume 1.08 x 10^21 m3, was composed of water. How long would it take for the Earth at 0°C to reach 100°C, if none of the energy was radiated or reflected back out into space...
Ah, i must have read the question too quickly. Earlier in the homework assignment there was a question that involved an object reaching terminal velocity and then continued falling, allowing for further temperature change. I assumed it had the same conditions as the earlier problem. Thanks!
Homework Statement
A block of material of mass m and specific heat c falls from height h and reaches speed v just before striking the ground. Its temperature is measured immediately after it strikes the ground. If we ignore any change in temperature owing to interaction with the air, the...
