Answer:
2)primary mirror
Explanation:
A reflecting telescope contains mirrors and a refracting telescope contains lenses. There are two mirrors in basic reflecting telescope. The primary mirror gathers the light from the bodies at distance and reflects it towards the secondary mirror. The secondary mirror is placed at such an angle that it then reflects the light towards the eye piece and we can observe the faraway body.
F = ma
f/m = a
9/0.1 = 90 m/s^2
so the answer is 90 m/s^2
What are the statements? both of the objects do move attract and maybe that is the answer
This one is nice and straight forward :)
simply calculate how many seconds are in 4.8 minutes like this:
4.8min x 60s = 288s
Then to find the ∆v (∆v = symbol for change in velocity) multiply the acceleration 0.0050m/s^2 by 288s
∆v = 1.44m/s
0.0050m/s
It is false that our resources can only supply a small fraction of our wants.
Although many resources we have are not renewable, we still have enough goods to meet our every need, at least for now. It may not be so in the future, but for now, we are good.
