Question

The gamma factor is defined as gamma = 1/ 1-(v/c)2, therefore gamma (Y) can be any number greater than or equal to one. can be zero. cannot equal one. can be any number less than or equal to one. A boat can travel 4.0 m/s in still water. With what speed, relative to the show, does it move in a river that is flowing at 1.0m/s if the boat is heading upstream? 4.1 m/s 5.0 m/s 4.8 m/s 3.0 m/s If you were to measure your pulse rate while in a spaceship moving away from the Sun at a speed close to the speed of light, you would find that it was much faster than normal. the same as it was here on Earth. much slower than normal. One of Einstein's postulates in formulating the special theory of relativity was that the laws of physics are the same in reference frames that move at constant velocity with respect to an inertial frame. are stationary, but not in moving frames. accelerate. oscillate.

Explanation / Answer

1) Since the velocity v is always less than light velocity, the factor (1-(v/c)2) is always less than or equal to one , So gamma is always equal to or greater than 1. So the answer is (a)

Ans. (a)

2) sqrt (42+12) = 4.1 m/s

Ans . a

3) You are measuring pulse in your frame, So it doen't change

Ans. (b)

4) Ans (a)
