A turntable of mass 100 g and radius of 20 cm is spinning freely at a constant angular speed of 33:3 rpm. A frictional force of 0:01 N is applied tangentially to its edge so that it eventually comes to rest. An ant of mass 0:1 mg is on the turntable a distance of 10 cm from the center of rotation. Find (in standard metric units, i. e., mks)

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
