How fine do you want them categorized for the ranking ?
What's the population to be ranked ?
The 4000 naked-eye-visible stars ?
The stars within, say, 50 light years from Earth ?
All 200-400 billion stars in the Milky Way galaxy ?
All the stars in some other galaxy ?
Or did you have a list of items to be ranked that you decided not to share ?
That would be a lot like asking us to seat a class of sixth graders alphabetically,
and then not telling us their names.
And how do we drag one star on top of another ?
And if I do that here, how will you know about it ?
They travel at the same rate of speed
Answer:
larger, because her angular speed is larger.
Explanation:
The rotational kinetic energy is proportional to the square of the angular velocity while it is linearly proportional to the moment of inertia. So the increase of angular speed will have a larger effect of the kinetic energy than the decrease of the moment of inertia.
W=Fd
W=22,000N*(2,000m)
W=44,000,000J
Answer:
The gravitational force between these two objects is around 
Explanation:
The gravitational force can be written as:

Here:
- G is the gravitational constant

- m(1) is the first mass
- m(2) is the second mass
- r is the distance between two bodies.
If we see, the gravitational constant is a very small number, therefore the gravitational force is representative just when we have to massive bodies. Let's suppose that the mass of the pencil is 0.1 kg and the eraser is 0.1 kg too, the distance between them would be around 10 cm or 0.1 m, for instance.
Now let's calculate the gravitational force of these two bodies.
As we see it is very small force, so it is negligible relation to the earth gravitational force. That is why these two objects do not move towards each other.
I hope it helps you!
