Avery delicate sample is placed 0.150 cm from the objective lens of a microscope. the focal length of the objective is 0.140 cm, and that of the eyepiece is 1.0 cm. the near-point distance of the person using the microscope is 25.0 cm. the magnitude of the final magnification of the microscope is closes to:

m = 14*26 = 364

Explanation:

overall magnification is given as m

mo magnification of objective lens

me magnification of EYE lens

where mo is given as

and me as

d is distant of distinct vision = 25.0 cm for normal eye

fe =  focal length of eye piece

focal length of objective lense is 0.140 cm

we know that

m = 14*26 = 364

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
