Q1. The specific heat of lead is 128 J/kg0C. 300 grams of lead shot at 1000C is mixed with 200 grams of water at 00C in an insulated container. What is the final temperature of the mixture?
Q2. Two identical carts travel at 1m/s in opposite directions on a common horizontal surface. They collide head-on and are reported to rebound, each with the speed of 2m/s. Then:
A. momentum was not conserved; then, the report must be false
B. if some other form of energy were changed to kinetic during the collision, the report might be true
C. if the collision were elastic, the report might be true
D. if friction were present, the report can be true
E. if the duration of the collision were long enough, the report might be true
