Question

A clock is placed aboard Starship Alpha, which Albert flies past Earth at half the speed of light relative to Earth. Elena observes from Earth, where she has an identical clock. Which pair of words correctly fills in the blanks of the statement, "Elena measures Albert’s clock as running ______________________ , and Albert measures Elena’s clock as running ______________________________ ."

Answer 1

Answer:

Slow , Slow

Explanation:

Here, according to both of them

the other is moving with a speed of half the speed of light

each of the observers would perceive the other's clock as ticking at a slower rate than their own local clock, due to them both perceiving the other to be the one that's in motion relative to their own stationary frame of reference

hence , the answer is slow and slow
