To solve this problem, we use the formula:
F = G m1 m2 / r^2
where F is gravitational force, G is constant, m1 and m2
are masses while r is the distance between the two asteroids
Since G m1 m2 is constant, therefore:
F1 r1^2 = F2 r2^2
So if r2 = 2 r1:
(1,000,000 N) (r1^2) = F2 * (2 r1)^2
<span>F2 = 250,000 N</span>

I think it’s 10 kg since 20/2=10
Magma<span> is made up of molten rock, and it is stored in Earth's crust. </span><span> When the volcano erupts, magma flows out of the volcano, it is usually mixed with steam and gas, which is called lava.</span>
Answer:
D
Explanation:
A and C are balanced, B has a resultant force of 5N right, and D has a resultant force of 20N right.
Answer:
0 m/s
Explanation:
velocity= change in displacement/ time
at rest, the ball does not travel any distance
0/ t
=0
