During a baseball game, a player hits a a ball with a speed of 43m/s at an angle of 25∘ above the horizontal. When the player hit the ball, it was 1m above the ground, and after the hit, the ball flies straight toward the center field fence.

How does the electric potential energy change as the electron moves from i to f?

A sound wave travels twice as far in neon (Ne) as it does it krypton (Kr) in the same time interval. Both neon and krypton can be treated as monatomic ideal gases. The atomic mass of neon is 20.2 u, and that of krypton is 83.8 u.
