Question 4 (1 point) A spinning disc has a moment of inertia of 1.5 kgm and is spinning at a rate of 14 rad/s. If a 0.5 kg blob of clay is dropped on it 1.5 m from the
center, what is the new angular speed?

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
