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.

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?
Verify that the solution in Example 1 in the discussion is related through time dilation with γ = 30.00 as given. Example 1:
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? The following approximation will prove useful: z 1 1 + x for x << 1. 2 - (Complete the equation for your answer.)

I am currently working through a physics book (Spacetime Physics by Edwin Taylor) and I have come across this question and I don't know how to solve it: "Take the differential of this equation for g to obtain an approximate algebraic expression for Δg, the change in g, for a small change Δr in height." How do I sovle this question?
