TRUE AND FALSE QUESTIONS IN PHYSICS 6. Change in mass affects KE more than a change in velocity
7. For acceleration due to gravity on Earth (g), we use 9.8 m/s^2
8. In a closed system, we can say that the maximum amount of Kinetic Energy must equal the maximum amount of Potential Energy in a different part of the closed system
9. The P in GEWAUP stands for Practice. 10. 1st Law of Thermodynamics states that energy cannot be created or destroyed.​

The momentum of an isolated system is conserved a) only in inelastic collisions. b) only in elastic collisions. c) in both elastic and inelastic collisions

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

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?
