The moon goes around the earth once every month. Assume for simplicity that one month is 27 days and the moon is a distance R from the center of the earth. A thin converging lens has a focal length of 30 cm. An object is 45 cm to the left of the lens. The mass oscillates with an amplitude of 10 cm.
White light is incident on a glass prism as shown.
The light breaks up into colors, three of which are shown in the figure. A concave mirror forms a real image which is twice the size of the object. 2.5 J 200 J Two equal masses approach each other with equal speeds. The masses collide and stick together. A 10 gram bullet is fired at a 1 kg block of wood that is initially standing still.
