Answer: D. 0.57
Explanation:
The formula to calculate the eccentricity of an ellipse is (assuming the moon's orbit in the shape of an ellipse):
Where:
is the apoapsis (the longest distance between the moon and its planet)
is the periapsis (the shortest distance between the moon and its planet)
Then:
This is the moon's orbital eccentricity
First calculate the the force per kilogram(0.25 / 20 or 80N) so 80m/s^2

Explanation:
the answer is B.=Kinetic-mechanical-electrical
Answer:
Explanation:
Gravitational potential energy = mgh where m is mass , g is acceleration due to gravity and h is height .
mg = weight so
Gravitational potential energy = weight x h ( height )
Putting the given values
Gravitational potential energy = 300 x 3
= 900 J .
