Question

What type of motion is observed in the substance during the time duration of 0 to 4 hours?​

Answer 1

Answer:

Explanation:

If an object is not changing relatively to a given frame of reference, the object is said to be at rest, motionless, immobile, stationary, or to have a constant or time-invariant position with reference to its surroundings. As there is no absolute frame of reference, absolute motion cannot be determined.[1] Thus, everything in the universe can be considered to be in motion.
