"What is the magnifying power of an astronomical telescope using a reflecting mirror whose radius of curvature is 5.9 m and an eyepiece whose focal length is 2.7 cm

The Magnifying power of a telescope is

Explanation:

Radius of curvature R = 5.9 m = 590 cm

focal length of objective =

⇒ =

⇒ = 295 cm

Focal length of eyepiece = 2.7 cm

Magnifying power of a telescope is given by,

therefore the Magnifying power of a telescope is

dang that balls went far

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
