Question

The Moon and Earth interact through their mutual gravitational forces. The Moon's rotation rate and the ocean tides on Earth are consequences of the gravitational tidal forces exerted by each body on the other. Considering the Moon, rank the gravitational tidal force exerted on it by Earth for three different lunar locations.

Answer 1

As explained below

Step-by-step explanation:

• The acceleration by the gravity of the moon is 1.625 m/s2 and is 16.6% on Earth's surface, and as an effect of the gravity, there are three different tidal bulges as diurnal, one high and low tide each day.

• When the moon is at a quarter phase i.e the right angle with the sun the gravitational bulges on earth produce tides are lower and these are called neap tides.

• During the period of new and full moon, there are high tidal bulges. As here both the sun and moon are in a straight line so high tides are produced this is called a spring tide.

• The waxing gibbous and crescent i.e the period when the moon is getting into the full or a new moon shape and thus there is mixing of tides. So it rises and declines until it reaches the complete potential.
