B) Energy
C) Time
D) All of these

Question

Quizplus · Accepted Answer

According to special relativity, all physical properties, including length, energy, and time, are dependent on the observer's speed. This is because special relativity shows that space and time are interconnected, and measurements of these properties will differ depending on the relative motion of the observer. This is exemplified in phenomena such as time dilation and length contraction. Therefore, all of the choices are dependent on the observer's speed.
