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]

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
