Explanation:
At the top of the tree, the velocity of the pebble is purely horizontal so we can calculate it as
Water is completely filling black metallic vessel having cubic form and thin walls. The mass of water is 1 kg and initial temper
ature 50 C. This cubic vessel is placed into black cavity whose walls are kept at the constant temperature of 0 C. Find time t it takes for the water to cool down to 10 C. Water specific heat is 4200 (J/kg K-1 .) After you find an answer, estimate whether this radiation mechanism would be responsible for the real-life water cooling and what other mechanisms might be in play.
