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

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
