Answer:
The temperature begins to increase with altitude in the stratosphere. This warming is caused by a form of oxygen called ozone (O3) absorbing ultraviolet radiation from the sun.The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude.
Explanation:
The PERIMETER of the equator cycle is about 40,000Km. The Greenwich cycle is a bit shorter as the earth is a bit an ellipsoid. About 37,000Km by Google Maps. The distance on the envelope between ANY antipodes (=opposite points on the axis, I won't use "diameter" to avoid confusion) is HALF the perimeter (If you walk the whole perimeter long, you'd get to the same point, of course). The distance through Earth is
D=P/Pi=37,000Km/Pi=about11777Km
.
Newton's 2nd law of motion says: <u>Force= (mass) x (acceleration)</u>
You know the force and the mass, and you need to find the acceleration.
So divide each side of the formula by (mass).
Then you have:
(force) / (mass) = acceleration .
Write the quantities that you know in their places,
and bada-bing, out falls the answer you need.
