Answer these questions.

imagine three cities in the desert, all at about the same altitude and latitude.

one city (a) is surrounded by a dark-colored rocky surface.

another city (b) is surrounded by a light-colored sandy surface.

the third city (c) is built on the edge of a large man-made desert lake.

1. which city would likely have the highest average summer air temperature and why?

2. the earth's surface tends to lose heat in winter. which of the above cities would have the warmest average winter temperature? why?

3. since the sun is approximately 93 million miles from the earth and space has no temperature, how do we get heat from the sun?

4. how would the uneven energy absorption by different surfaces on earth (water, soil, snow, trees, sand, etc.) affect the atmosphere?

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
