A charged particle moves through uniform electric and magnetic fields. Which is true about the magnetic force and the electric force acting on the particle? Neither force depends on the speed of the particle. Both forces depend on the speed of the particle. The magnetic force depends on the speed; the electric force does not depend on the speed. The electric force depends on the speed; the magnetic force does not depend on the speed.

Which feature of a heating curve indicates a change ofn state

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

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?
