A radius 64.0 cm concave spherical mirror is used to project an image on a screen 3.50 m away. (a) calculate the object distance from the mirror. (b) Calculate the magnification of the image. (c) is the image erect or inverted? You want to form an image of a postage stamp double the actual size of the stamp by using a magnifying glass of focal length 30.0 cm. What is the distance of the stamp from the lens?

8. A satellite is in circular orbit about planet Rosseforp at an altitude (above the surface) h. When h = 1.75 × 104 km, the period of the orbit is T = 12 hours. If Rosseforp has a mass of 7.0 × 1024 kg, what does the satellite weigh on the surface of Rosseforp if it weighs 850 N on the surface of Earth? You are part of an expedition to planet Rosseforp (same planet as in the previous question)....
