The refracting telescope at the Yerkes Observatory has a 1.00-m diameter objective lens of focal length 20.0 m. Assume it is used with an eyepiece of focal length 2.50 cm. (a) Determine the magnification of Mars as seen through this telescope. (b) Are the Martian polar caps right side up or upside down

a) -800

b) inverted

Explanation:

Given

Focal length of the lens, f(0) = 20 m

Focal length of the eyepiece, f(e) = 2.5 cm = 0.025 m

The astronomical telescope uses two positive lenses: the first one being the objective, it forms the image of a distant object at its focal length, the second being, the eyepiece, it acts as a simple magnifier through which you view the image formed by the objective.

a) Magnification of Mars as seen through the telescope is

M = -f(0) / f(e)

M = -20 / 0.025

M = - 800

b) Since the magnification produced by the lens is less than 0 i.e m < 0, m = -800, suffice to say, the image is inverted.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
