What are the benefits for a hospital to organize itself as a nonprofit? Do nonprofits make less money than for-profit hospitals? Do some quick research on the internet and see which major hospitals near you (or near a city you have lived in within the U.S.) are nonprofits. Can you find information on CEO compensation? Do they seem to make less than CEO's of for-profit hospitals? Does the hospital (or hospitals) you chose seem to be fulfilling its (or their) obligations to benefit the community? How do they do so?

A magnifying glass is a single convex lens with a focal length of f = +9.50 cm. (Assume the person using the magnifying glass has a near point of 25 cm and the magnifying glass is directly in front of the person's eyes.)

(a) What is the angular magnification when this lens forms a (virtual) image at ???


How far from the object should the lens be held?


(b) What is the angular magnification when this lens forms a (virtual) image at the person's near point?


How far from the object should the lens be held in this case?

Suppose that you decided to send a spacecraft to Neptune using a Hohmann transfer. The craft starts in a circular orbit close to the Earth (1 AU) and is to end up in a circular orbit near   Neptune (about 30 AU).   (a) How long would the transfer take?   (b) How could you shorten this time, without increasing the amount of fuel required?   (c) What change in velocity is needed to enter the transfer orbit?   (d)   What is the change in velocity needed to enter the circular orbit near Neptune?
