Answer:

a. They are typically operated at lower temperatures.b. They are especially helpful for viewing cool or obscured astronomical objects.
B. The resistance is directly proportional to length and inversely proportional to cross sectional area
Answer:
The greater weight increases the terminal velocity by acting as an extra force against gravity and air resistance.
Explanation:
A one-kilogram mass is still a one-kilogram(as mass is an intrinsic property of the object) but the downward force due to gravity, and therefore it's weight, is only one-sixth of what the object would have on the Earth. So man of mass 180 pounds weights only about 30 pounds-force when visiting the moon
hope it help..... pls add me as brainlist.
Have a nice day
