A solar day is the time interval between two successive appearances of the sun overhead. The time that is referred to the rotation of the earth about its axis is called:
Correct answer: A. Universal Time
- A. Universal Time
- B. Length of the day
- C. Time interval
- D. Solar day
Explanation
A solar day is time lnterval between two successlve appearance of the sun overhead. Thus mean second, representing the basic unit of time, was originally defned as (1/60) (1/60) (1/24) of a mean solar day. The tme that is referred to rotation of the earth about its axis is called universal time. STB-Chapter#1.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
