To change a tire, you need to use a jack to raise one corner of your car. while doing so, you happen to notice that pushing the jack handle down 20 cm raises the car only 0.2 cm. use energy concepts to explain why the handle must be moved so far to raise the car by such a small amount.

Which is an example of an exothermic process?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
