Answer:
a. The Special relativity postulate states that the laws of physics apply in all inertia frames of reference
b. General relativity must be uses a curved space-time
c. Time is dilated for a stationary observer relative to one in motion
Time interval observed on an object in a moving frame of reference is less than the same interval observed on a stationary reference frame
[tex]\Delta t' = \dfrac{\Delta t}{\sqrt{1 - \dfrac{v^2}{c^2}}}[/tex]
Length is contracted
The length of a rod moving with a velocity relative to an observer will appear contracted by a factor [tex]\sqrt{1 - \dfrac{v^2}{c^2}}[/tex], in the direction of the motion.
