An uncharged conductor has a hollow cavity inside of it. Within this cavity there is a charge of +10 μC that does not touch the conductor. There are no other charges in the vicinity. Which statement about this conductor is true? (There may be more than one correct choice.) (a) The inner and outer surfaces of the conductor each contain charges of -5 μC.

(b) The net electric field within the material of the conductor points away from the +10 μC charge.

(c) The outer surface of the conductor contains +10 μC of charge and inner surface contains -10 μC.

(d) Both surfaces of the conductor carry no excess charge because the conductor is uncharged.

(e) The inner surface of the conductor carries a charge of -10 μC and its outer surface carries no excess charge.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
