Question 1

An all-terrain vehicle of 2000 kg mass moves up a 15.0° slope at a constant velocity of 6.00 m/s. The rate of change of gravitational potential energy with time is

◦
5.25 kW.

◦
24.8 kW.

◦
30.4 kW.

◦
118 kW.

◦
439 kW.


Question 2

An astronaut tosses a ball out in space where gravitational forces may be neglected. What will happen to the ball?

◦
It will stop as soon as the force the astronaut gave it is used up.

◦
It will stop when the energy the astronaut gave it runs out.

◦
It will stop after a short time because there is no gravity to keep it moving.

◦
It will move in a circle like a boomerang.

◦
It will be slowed down very gradually by collisions with molecules in space.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
