In science, Bob learns that the energy of a wave is directly proportional to the square of the waves amplitude. If the energy of a wave is 4 J, what should he predict as the amplitude of the wave?

A closed system of mass 10 kg undergoes a process during which there is energy transfer by work from the system of 0.147 kJ per kg, an elevation decrease of 50 m, and an increase in velocity from 15 m/s to 30 m/s.

When energy from the Sun reaches the air above land, the air warms and rises. Along a coastline, cooler air above the ocean flows towards land to replace this rising air. What types of heat transfer are taking place during this process?
