Question

What is true in Einsteins SPECIAL RELATIVITY, choose one of the three alternatives each for a) - d)

a) EVENTS (1. Are affected by our choice of reference frame - 2. Defines spacetime - 3. Only has one set of coordinates in space and time)

b) WRISTWATCH TIME MEANS (1. The time you measure in your own reference frame - 2. The time measured by an observer for an arbitrary object - 3. That relativistic affects only impacts watches and does not affect biological processes)

c) THE TIME-INTERVAL BETWEEN EVENTS (1. Is equal for all - 2. Can be different - 3. Cannot be measured)

d) THE WORLDLINE FOR AN OBJECT (1. Tells the full story between two events - 2. Describes its path through space - 3. Depends on which reference frame we choose)

Answer 1

a) EVENTS- 2.defines spacetime.

b) WRISTWATCH TIME -1. is the time you measure in our own reference frame.

c) THE TIME-INTERVAL BETWEEN EVENTS -2.can be differ for diffrent refrence frame. Moving clock runs slow i.e. time interval can be dialated in moving refrence frame.

d)  THE WORLDLINE FOR AN OBJECT-1.tells the full story between two events. It does not deped on frame.

I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks...
