Amicroscope includes an objective lens (with focal length of f_o = 1cm) and an eyepiece (with f_e = 3cm). the distance between two lenses is d = 20cm. compute: the angular magnification power of the microscope. where an observation slice (object) should be placed (the distance between the slice surface and the objective lens) in order to make the final image located 25cm left of the eyepiece?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
