What magnification would be obtained if an eyepiece with a focal length of 0.38 m was placed on telescope?

This question is incomplete

Explanation:

This question is incomplete because the telescope's focal length was not provided. The formula to be used here is

Magnification = telescope's focal length/eyepiece's focal length

The eyepiece's focal length was provided in the question as 0.38 m.

NOTE: Magnification can be described as the power of an instrument (in this case telescope) to enlarge an object. It has no unit and thus the two focal lengths mentioned in the formula above must be in the same unit (preferably meters since one of them is in meters already).

we need to know the time interval during which the force acts. impulse of force = momentum change

the answer is 12 as i may remember
