9 The force F keeping the moon in its orbit round the earth is inversely proportional to
the square of the distance r from the earth.
If F = 6 x 105 KN, and r = 8 x 108 m,
Find: 1
(a) the equation connecting F and r
(b) ) the value of F when r = 16 x 108 m
(c)
the value of r when F= 24 x 109 KN.

what tree

explanation:

1. law of superposition: when there are horizontal layers of rock. the layers at the top are the youngest.

2. law of uncomformity: where one layer is much younger than the previous one, therefore creating a gap in the time record.

3. inclusion: when there is a solid stone inside of another.

4. intrusion: a feature formed when a stone is filled with magma.
