While on vacation, Paul is staying in a hotel room with a balcony 18.0 m above the ground that is overlooking the ocean. He is curious as to how far he could throw a
rock before it hits the water. Recognizing that it would be unsafe to actually throw
the rock, he decides to work out the answer mathematically. He knows that he can
throw the rock horizontally at a speed of 30.0 m/s. How far from the hotel will the
rock be when it hits the
water?

I’ve asked this 3 times now so you can go. On my account and copy and paste ur answers to get all the points pls I rlly need this

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
