Explanation:
Solution,
Volume (v)=287 cm^3
Mass(m)=816 g
Density(d)=m/v
=816/287
=2.84
So, the density of the block of marbles is 2.84 g/cm^3.

Answer:
That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.
Explanation:
They will both hit at the same time there isn't any air resistance on the moon <span />
The tangent of that angle is 17.63/100 = 0.1763 .
My calculator says that the angle with that tangent is 9.9985° .
10° is awfully close, and it's a much easier answer.
(It's less than 0.015% wrong.)
