Answer:
Explanation:
The density changes means that the length in the direction of the motion is changed.
Therefore,
Given :
Side, b = h = 0.13 m
Mass, m = 3.3 kg
Density = 8100
So,
l = 0.024 m
Then for relativistic length contraction,
Therefore, the speed of the observer relative to the cube is 0.9833 c (in the units of c).
