Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that orbital velocity at certain height from the surface of Earth is given as

here we know that



now we have


Part b)
When a loose rivet is moving in same orbit but at 90 degree with the previous orbit path then in that case the relative speed of the rivet with respect to the satellite is given as

Answer:
Part a)

Part b)

Part c)

Part d)

Explanation:
Part a)
As we know that the orbital speed of the satellite is given as

now we will have

now we have


now we have


Part b)
Here force between mars and satellite is the gravitational attraction force which is given as



Part c)
Acceleration of satellite is the ratio of gravitational force and mass of the satellite



Part d)
As we know by III law of kepler

here we know that T2 = 8 T1


so we have

as we know that speed is given as

so we can say since radius is orbit becomes 4 times so the orbital speed must be half

Answer:
a)
b)
Explanation:
The gravitational force on the satellite is calculated with Newton's Gravitation Law:

Where
is Earth's mass,
is the satellite mass,
is the distance between their centers, where
is the height of the satellite (from Earth's surface) and
is Earth's radius, and
is the gravitational constant.
a) With these values we then have:

b) And the fraction this force is of the satellite’s weight <em>W=mg</em> is:
