A student collected information about air masses from the model. She learns that air masses are huge bodies of air that form over
water or land in tropical or polar regions. They may extend across
an entire continent and are relatively uniform in temperature and
moisture content. What happens as an air mass moves over any
particular area?

A The characteristic of the air mass changes along with the weather of that area.
B The characteristic of the air mass along with the
weather of that area remain the same.
C The underlying vegetation and water bodies’ characters in that area remains the same and no change occurs.
D There will be many days of drought in that area.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.

You notice the birds sitting on the electrical wires which of the following explain why the birds don't get shocked

A0.25 kg arrow is moving at 5 m/s and hits a 0.10 kg apple. the apple sticks to the arrow, and both move to the right together. what is their velocity?
