Albert views henry moving by at a constant velocity. henry has a light clock and also a stopwatch which were synchronized when at rest. as albert views these two moving clocks, which of these statements would be true according to albert? the light clock runs slow compared to the stopwatch. the stopwatch runs slow compared to the light clock.

The two are still synchronized but run slow

Explanation:

Time flows at a different rate for an object that is moving. The time of the object which is moving is running slower than an object which is stationary. Here, Albert is stationary so time will flow faster for him and for Henry who is moving time will flow slower. This phenomenon is called time dilation

Where,

Δt is the time elapsed for the person who is moving

Δt' is the time elapsed for the person who is stationary

c = Speed of light = 3×10⁸ m/s

v = Velocity of the object which is moving

the device is called “ rocket engine”
