At 1:00 PM, Sally puts into a refrigerator a can of beer that has been sitting in a room temperature 70°F. The temperature in the refrigerator is 40°F. Fifteen minutes later the temperature of the beer has fallen to 60°F. At some later time, Sally removes the beer from the refrigerator to the room, where at 2:00 PM the temperature of the beer is 60°F. At what time did Sally remove the beer from the refrigerator?
How does temperature affect the time measured by a pendulum clock? More precisely,
consider a clock that uses a simple pendulum. The pendulum consists of a thin metal rod
of length l. Recall that the angular frequency of a simple pendulum is w = g/l.
Suppose on a hot day, the temperature is considerably above “average." How does the
increased temperature affect the clock?
a) The clock runs slow. So it reports a time behind actual time.
b) The clock runs fast. So it reports a time ahead of actual time.
c) The clock is not affected by the temperature.
d) The answer depends on the mass of the simple pendulum.

- In order to increase the fuel efficiency and reduce structural failure of airplanes, new composite materials have been designed to replace airplane fuselages made of aluminum. Composite materials are low in density and tolerant to damage. One drawback of this new material is that it is not conductive. This increases the chance that a lightning strike will damage the plane. Engineers have redesigned the composites by adding a material to the original composition that is conductive. Identify one anticipated effect of this new material. Explain why the addition of the new material to the composite fuselage design will result in a tradeoffarrow_forward25 The deepest point in Earth’s oceans is about 11,000 m below the surface of the water.
