What is difference between angular acceleration and centripetal force? How moment of inertia is related to torque? An elevator starts up from the basement with initial acceleration of 16m/sec² will the passenger's apparent Bwl-17 Sgd-16 weight be increased, decreased or remain same. An elevator moving down when suddenly the chain of the elevator breaks. Two different bodies appear to Lhr-17 having the same weight. What is the real weight and why? SECTION II ot any 3 (three) questions. Mul-16 Explain the angular momentum? Differentiate between spin angular momentum and orbital angular momentum? Explain law of conservation of angular momentum (5) What is least speed at speed at which an aero plane can execute a vertical loop of 1.0km radius so that there is no tendency for the pilot to fall down at the highest point? Dgk-15,17, Lhr-16, Bwl-16, Guj-18 What do you mean by instantaneous angular acceleration? Calculate centripetal force. (5) Radio and TV signals bounce from a synchrono...
