If you place 48 cm object 15 m in front of a convex mirror of focal length 5 m, what is the magnification of the image?

m = 0.25

Explanation:

Given that,

Object distance, u = -15cm

Height of the object, h = 48

Focal length, f = cm

We need to find the magnification of the image.

Let v is the image distance. Using mirror's equation.

Magnification,

Hence, the magnification of the image is 0.25.

d) the number of neutrons plus the number of protons
