As the moon revolves around the earth, it also rotates on its axis. why is it that the same side of the moon is always visible from earth? a. the speed of the moon's rotation keeps the same side always facing earth. b. the earth's gravity attracts one side of the moon more than the other. c. that side of the moon only faces away from earth during the daytime. d. the moon does not have a day and night cycle.

A. The speed of the Moon's rotation keeps the same side always facing Earth.

Explanation:

Earth has one natural satellite - the moon. The same side of moon is always visible from the Earth because period of rotation around its axis and revolution around the earth are almost same. Moon rotates about its axis  and around the earth in about 28 days. The speed of the Moon's rotation keeps the same side towards the Earth.

Thus, correct option is A.

come closer and become far apart and become steam/gas

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
