I really need these points thx a lot
Answer:
A. absorption of ultraviolet rays from the Sun
Explanation:
The thermosphere helps protect and regulate Earth's temperature by absorbing much of the UV radiation and X-rays emitted by the Sun. When the Sun is most active, the thermosphere heats up and increases in size, increasing its protective power.
Just like in the oceans, the Earth's atmosphere experiences waves and tides that help move energy within it. The winds and the general circulation of the thermosphere are strong drivers of these tides and waves.
Answer:
a)
b)
c)
Explanation:
a) The angular velocity is related to the centripetal acceleration by the formula
, which for our purposes we will write as:

Since <em>we want this acceleration to be 1.5 times that due to gravity</em>, for our values we will have:

b) 1 rpm (revolution per minute) is equivalent to an angle of
radians in 60 seconds:

Which means <em>we can use the conversion factor</em>:

So we have (multiplying by the conversion factor, which is 1, not affecting anything but transforming our units):

c) The centripetal force will be given by Newton's 2nd Law F=ma, so on the centripetal direction for our values we have:
