An object is placed on a common central axis of two thin lenses. The distance from the object to the first lens is 19 cm. The distance between the two lenses is 35 cm. The first lens is a converging lens with a focal length of 9.9 cm. Thesecond lens is a diverging lens with a focal length of 9.0 cm. What is the magnification of the system?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
