The answer is "have elliptical orbits"
The planets in our solar system including our home planet earth have an elliptical orbits instead of circular orbits. Because the circular orbits represents the perfect balance in velocity and gravity force. Planets differs in distance from the sun. Also, the planets are not measured in light years.
Answer:
Prob. D

Answer:
I =1.8 kgm^2
Explanation:
In order to calculate the moment of inertia of the door you use the following formula, which relates the torque applied to the door with its moment of inertia and angular acceleration:
(1)
τ: torque applied to the door
I: moment of inertia of the door
α: angular acceleration = 5 rad/s^2
The torque is also given by τ = Fd, where F is the force applied at a distance of d to the pivot of the door (hinge axis).
F = 10 N
d = 0.9 m
You replace the expression for τ, and solve for I:
The moment of inertia of the door is 1.8 kgm^2
I believe the answer is "power generators"
