Which statement is supported by einstein’s postulates of special relativity? the laws of physics change, depending on the state of motion of the observer. the laws of physics change, depending on the reference frame of the observer. the speed of light through empty space is constant regardless of the state of motion of the observer. the speed of light through empty space depends on the state of motion of the observer.

The speed of light through empty space is constant regardless of the state of motion of the observer supports Einstein’s postulates of special relativity.

Explanation:

Einstein gave two postulates, based on which he could put forward Special Theory of Relativity.It majorly tells us about the events depending on an observer.

The second postulate talks about the speed of light. The Speed of light for all observers is constant in an empty space or vacuum, i.e., 3× m/s. It does not matter whether the course of light is moving or not.

no image, but probably absorption

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
