During a baseball game, a high fly ball is hit into the outfield. The ball leaves the bat at a velocity of 44.7 m/s at an angle of 20 degrees (relative to the horizontal). 1. How long is the ball in the air if caught at the end of its range.? Show all work.
2. What is the maximum distance that the ball will go assuming it is caught at the same level as it was hit? Show all work.
3. What is the maximum height the ball rose relative to its starting point? Show all work.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
