Answer:
∠EGF = 90°
Explanation:
Question is incomplete as the attachment is missing.
To solve this I'll make an assumption that ∠EGF is an angle inscribed in the circle.
Given that
Line EF is a diameter;
Then the arc formed by EF is 180° (semi circle).
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
So, the inscribed angle
Arc EF = 2 * ∠EGF
Make ∠EGF the subject of formula
∠EGF = ½ EF
∠EGF = ½ * 180°
∠EGF = 90°
The cause is the fact that they have orbits of different size.
For two objects in orbit around the same central body, the one in the
larger orbit will take longer for each complete revolution.
And if two objects are in the same-size orbit, their periods of revolution
are identical, even if the objects have different size and mass.
(Example: All TV satellites are in the same orbit. Some are big and heavy,
some are smaller and lighter, but all of them revolve around the Earth in
exactly 24 hours.)
