If the magnification power on your microscope's objective was 40x and the magnifying power on the eyepiece was 10x, the total magnification would be a.50x b.30x c.400x d.40x

Total magnification, m = 400 X

Explanation:

It is given that,

Magnification power on microscope's objective, m₁ = 40 X

Magnifying power on the eyepiece, m₂ = 10 X,    

We have to find the total magnification. Total magnification of an image is given by the product of microscope's objective and magnifying power of the eyepiece i.e.

m = m₁ × m₂

m = 40 X × 10 X

m = 400 X

So, the total magnification would be 400 X. Hence, the correct option is (c) "400 X".

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
