You can face these in Exam or Entry Tests The orbit of an artificial satellite is elliptical? The required tangential velocity of the orbiting satellite should be greater for larger radius? The spinning frequency of the orbiting spaceship to overcome the weightlessness is inversely proportional to inner radius of the spaceship? Communication satellites appear to be stationary at a point due to their time period of 24 hours? 1 Radian = 67? 30The angular acceleration of a body experiencing torque is directed?
The orbital velocity of a satellite orbiting around the earth is directly proportional to? A body moving counter clock-wise when slows down its angular acceleration will be? The acceleration of a body is … when it revolves in a circle with constant speed? In circular motion, the linear velocity, the radius and the angular velocity are …… to one another? Artificial gravity produced in an orbiting spaceship is to overcome the ………? ………… geostationary satellites can cover the communication system of the whole world? The linear acceleration is related to the angular acceleration by the relation a = …?
A body is moving in a horizontal circle under the action of centripetal force? Show that the work done on it is zero? A pilot experiences negative weight while flying a jet plane? What is the state of motion of the jet plane?The cylinders A and B are of the same mass but the radius of A is greater than that of B? Which one will require more force to come into rotation? Why?Satellites orbiting at different altitudes have different time periods? Explain Why?An elevator is moving down when suddenly the chains of elevator break? Two different bodies appear to be having same weight? What is their weight and Why?
