Adeep space probe travels in a straight line at a constant speed of over 16,000 m/s. assuming there is no friction in space, if a loose part were released from the spacecraft without a push in any direction, what would happen to it? a. it would slowly coast to a stop. b. it would head off on its own trajectory. c. it would stop immediately as soon as it was no longer in contact with the probe. d. it would continue along with the spacecraft.

Which statement best describes copper? a. it has a low resistance and prevents charges from moving freely. b it has a high resistance and allows charges to move freely. c. it has a high resistance and prevents charges from moving freely. d. it has a low resistance and allows charges to move freely

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction. true or false?
