1286 A car of rest length 15 ft moves at high speed through a garage with doors at each end. The rest length of the garage is 12 ft. S is the garage system and S' the car system. According to observer S, there is an instant (say t the car is entirely ins ide the garage, the ends of the car coinciding with the front and rear door frames of the garage. 0) at which simultaneously 11 (a) What...

A long wire that is at rest in the Earth reference frame initially carries no current. Observer E in this reference frame measures linear charge densities of ?En = 45.00 ?C/m for the (negative) electrons in the wire and ?Ep = 60.00 ?C/m for the positive ions. A current is created as electrons are made to move through the wire at speed v, M moves along with the electrons at their speed v. What value must v have in order...

Two clocks, labelled 1 and 2, are at rest in an inertial frame , S. They are synchronized and separated by a distance, d, as measured in S. A third clock, 3, at rest in S', moves from clock 1 to clock 2 at constant speed, v. An observer in S' measures the distance between clocks 1 and 2 to be 0.72 d. 10 seconds elapses on clocks 1 and 2 in the time taken for clock 3 to travel...
