A camera lens focuses on an object 75.0 cm from the lens. The image forms 3.50 cm behind the lens. What is the magnification of the image?

- 0.0466666667

Explanation:

We are told in the question above that:

A camera lens focuses on an object 75.0 cm from the lens. The image forms 3.50 cm behind the lens.

The formula for Magnification of an image = - image distance / object distance

Image distance = 3.50 cm

Object distance = 75 cm

Magnification = - 3.5/75

= -0.0466666667

= Approximately = -0.0467

Therefore, the magnification of the image is -0.0467

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
