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.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
