# Problem: Which of the following statements are true concerning special relativity? Check all that apply.A. Clocks moving relative to an observer are measured by that observer to run more slowly compared to clocks at rest.B. The laws of physics have the same form in all inertial reference frames.C. Light propagates through empty space with a definite speed independent of the speed of the source or observer.D. Time can no longer be regarded as an absolute quantity.E. The length of an object is measured to be shorter when it is moving relative to the observer than when it is at rest.

###### FREE Expert Solution

1. Time dilation - moving clocks run slow.
2. Length contraction - moving rods contract.
