If you knew that when the astroid had an acceleration of 2m/s^2 the two astroids were 30 m apart and could find the force on the one astroid, could you find the mass of the second astroid? don't do it, just say how.

What major reason has the capture theory been rejected as a understanding of how the earth acquired its moon?

Question 5

5.

Draw a picture to show why a comet, with its much more elliptical orbit have a significantly different speeds at aphelion and perihelion than a planet like earth whose orbit is almost, but not quite circular?

Explain why the tides works more like a pimple being popped than taffy being stretched.

In the middle of space, far away from any other object, two slow moving astroids get close to each other.  Astroid 1, a 1000kg which feels a force from astroid 2 starts accelerating towards astroid 2 at 3m/s^2 Using 
Where G = 6.67408 × 10-11 m3 kg-1 s-2, if you are asked to find the force of the astroid 2 on astroid 1, Which equation do you use? 

The earth is tilted towards the sun at aphelion, meaning

the northern hemisphere experiences summer farthest from the sun

The northern hemisphere experiences summer closest to the sun

the northern hemispheres summers and winters are more extreme than the southern hemispheres

Jupiter is on the same side of the sun as the earth
