g spaceship has a life support system that can keep its crew alive for 800 hours. The crew wants to travel a distance of 1x1015 m (as measured in the rest frame of the start and end points). es a pulse of light ~927 hrs to travel the same distance. Does this mean that the ship will have to travel faster than light? Explain why or why not. [1] b) How fast will the ship have to go so that it can travel 1x1015 m without depleting its life support system? Express your answer as a fraction of the speed of light. [4] Hint: 훾ଶ훽ଶ= ఉమଵିఉమ, where 훽= 푣/푐. c) How long did the trip take according to an observer at rest at the destination? [1]

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
