62. (a) Calculate the retarding force due to the viscosity of the air layer between a cart and a level air track given the following information—air temperature is 20º C, the cart is moving at 0.400 m/s, its surface area is 2.50×10−2m22.50×10−2m2, and the thickness of the air layer is 6.00×10−5m6.00×10−5m.
(b) What is the ratio of this force to the weight of the 0.300-kg cart?

A water drop slung onto a skillet with a temperature between 100°C
and 200°C will remain a liquid for about 1 second. However, if the
skillet is much hotter the drop can last several minutes. This is
due to the Leidenfrost Effect, named after an early investigator
(circa 1756). The longer lifetime is due to the support of a thin
layer of air and water vapor that separates the drop from the metal
(by a distance L, as shown in...

. Suppose a vertical pipe is to be used as part of a system to
manually cycle nutrients upward from the floor of a lake. (Many
lakes do this naturally, some do not. Green Lake, near Syracuse,
NY, is one such lake.) A pump is to be installed on the lake floor
at the base of the pipe. The base of the pipe will have a diameter
of 9 cm. The nozzle of the pipe at the top will have...
