A refrigerator causes a transfer of thermal energy from a cooler region to a hotter region. The separation of hot and cold causes an increase in order. The following two questions deal with this situation. 1.

27b. You're in an airplane that flies horizontally with speed 1000 km/h (280 m/s) when an engine falls off. Ignore air resistance and assume it takes 30 s for the engine to hit the ground.
