You are using a magnifier that gave you a lateral magnification of 1/2. if the object distance is 0.5 cm, calculate the focal length of the magnifier.

The focal length is -0.5.

Explanation:

Given that,

Magnification

Object distance u = 0.5 cm

We need to calculate the image distance

Using formula of magnification

Put the value into the formula

We need to calculate the focal length

Using formula for focal length

Hence, The focal length is -0.5.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
