A microscope has an objective lens of focal length+0.50-cm and an eyepiece of focal length+2.6-cm. An object is placed 0.60 cm in front of the objective lens. The final virtual image is100 cm from the eyepiece at the position of minimum eyestrain.
Part A. Determine the separation of the lenses. Assume that the near point distance is 25 cm. Express your answer to two significant figures and include the appropriate units.
Part B. Determine the total angular magnification. Express your answer using two significant figures.

A tire with an inner volume of 0.0250 m is filled with air at a gauge pressure of 36.0 psi (i.e. lb/in2). If the tire valve is opened to the atmosphere, what volume outside of the tire does the escaping air occupy?
At amusement parks, there is a popular ride where the floor of a rotating cylindrical room falls away, leaving the backs of the riders "plastered" against the wall. Suppose the radius of the room is 4.00 m and the speed of the wall is 10.4 m/s whe..
