Answer: If you solve for the orbit speed, v, in the mass formula, you can find how fast something needs to move to balance the inward pull of gravity: v 2 = (G M)/r . Taking the square root of both sides (you want just v not v 2), you get v = Sqrt.
Explanation:
The direction of a freely swinging pendulum changes during the day. That is also how we were able to prove that the Earth rotates.
c^2=a^2+b^2
C^2=12^2+4^2
c^2=144+16
C^2=160
C=12.6
I am not 100% sure this is right!!!!
<span>Scientists infer that most of Earth earliest atmosphere was produced by the escape of gases from Earth's molten surface. Once these gases were released from the very hot surface that covered the Earth, the earliest stages and levels of the atmosphere we know today were created. Many of those earliest gases still make up our atmosphere today.Hope this helps. Let me know if you need additional help!</span>
