Tidal friction is slowing the rotation of the earth. as a result, the orbit of the moon is increasing in radius at a rate of approximately 4.0 cm/yr. assuming this to be a constant rate, how many years will pass before the radius of the moon's orbit increases by 3.84x 10^7 m (10%)?

967500000 years

Explanation:

The Speed at which the radius of the orbit of the Moon is increasing is 4 cm/yr

Converting to m

1 m = 100 cm

The distance by which the radius increases is 3.84×10⁷ m

Time = Distance / Speed

967500000 years will pass before the radius of the orbit increases by 10%.

c. magnitude and direction

because growing process had stoped after 4-5 year
