A thin uniform cylindrical turntable of radius 2.3 m and mass 19 kg rotates in a horizontal plane with an initial angular speed of 7.1 rad/s. The turntable bearing is friction less. A clump of clay of mass 4.9 kg is dropped onto the turntable and sticks at a point 1.5 m from the point of rotation. Find the angular speed of the clay and turntable. Answer in units of rad/s.
How much heat does it take to increase the temperature of 4.50 moles of a diatomic ideal gas through an amount 40 if the gas is held at constant volume? The gas molecules can translate and rotate but not vibrate.
Find a circuit to change the relationship between waveform and zero-volt axis & calculating the period of waveform.
A compact disk player has just been turned off. A disk decelerates uniformly from an initial angular velocity of 8.30 rev/s. What is the tangential acceleration of a point on the disk 3.60 cm from the axis
