Choose the option from each pair that makes the followingstatement correct. Because y for an object in relative motionis always [(a) greater; (b) less] than 1, a proper time intervalAt, is always [(c) longer; (d) shorter] than the time interval Atand a proper length L, is always [(e) longer; (f) shorter] thanthe length L.

Lorentz factor for an object in relative motion is always greater than one.So option (a) is correct.

The proper length of one spaceship is three times that of another. The two spaceships are traveling in the same direction and, while both are passing overhead, an Earth observer measures the two spaceships to have the same length. If the slower spaceship has a speed of 0.354c with respect to Earth, determine the speed of the faster spaceship. (Give your answer to at least 3 significant figures.) |c
If ever the human race would need to leave Earth, the Trappist-1 system might make a good destination – the star there has seven temperate terrestrial planets, a few of which are close to Earth’s size and mass. It’s 39.6 light years away, though, so it could take a long time to get there. (a) If the spaceship had a speed of 0.95c, how long would the journey take from the Earth’s reference frame? (b) How long would the journey be for the passengers on the spaceship?
Determine an expression for the total travel time of the light pulse, as measured by the following: A) an observer in the S frame (Use the following as necessary: c, d, and v.)

For spacelike separated events show that: i) the two events cannot be causationally related, that is, there exists a reference frame such that the two events can occur simultaneously. ii) there exists no such reference frame where the two events can occur in the same (x, y, 2) location within space.
An astronaut wishes to visit the Andromeda galaxy, making a one-way trip that will take 25.3 years in the space-ship's frame of reference. Assume the galaxy is 2.00 million light years away and his speed is constant. (a) How fast must he travel relative to Earth?
