he distance between the eyepiece and the objective lens in a certain compound microscope is 22.5 cm. The focal length of the eyepiece is 2.40 cm and that of the objective is 0.385 cm. What is the overall magnification of the microscope

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
