An overhead projector lens is 32.0 cm from a slide (the object) and has a focal length of 30.1 cm. What is the magnification of the image? (Unit=cm) PLS HELP

M = 14.3

Explanation:

Given the following :

Object distance (u) = 32cm

Focal length (f) = 30.1 cm

Magnification = image distance (v) / object distance (u)

Recall ; 1/f = 1/u + 1/v

1/30.1 = 1/32 + 1/v

1/v = 1/30.1 - 1/32

1/v = (32 - 30.1) / 963.2

1/v = 2.1 / 963.2

1/v = 0.0021802

v = 1/0.0021802

v = 458.66666 cm

Therefore, Magnification 'M' = v / u

M = 458.66666 / 32

M = 14.333333

M = 14.3

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
