One of the advantages of operating a telescope above the earth’s atmosphere is that it can deliver diffraction limited images. the hubble space telescope, which has a mirror with a diameter of 96 inches, is used to observe a star system. we are interested in seeing if the star has a planet so we are looking in the red around . will the possible planet be resolved if it really exists and separation is 0.2 microrads from its parent star? also, why would we be looking for a planet in red light? would you recommend a different wavelength? if we can’t see the possible planet, how big of a telescope would be needed? the new webb space telescope will have a mirror with an 8 m diameter. is this enough?

no

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

find the sum of the two horizontal vectors and the sum of the two vertical vectors

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
