Identify all of the predominant forms of energy produced when each process occurs. Some processes may produce only one form of energy, whereas others may produce more than one form of energy.

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.

What is the quantity which is measured by the area occupied below the velocity- time graph?

The velocity of sound wave in air at 35°c is 353m/s, calculate the velocity of sound at 46°c
