A permanent magnet passes through a loop of wire. When is the electrical potential difference in the loop the GREATEST? a
When the permanent magnet is held far away from the loop of wire.
b
When the permanent magnet is passed slowly through the loop of wire.
When the permanent magnet is passed quickly through the loop of wire.
с
d
When the permanent magnet is held still in the middle of the loop of wire.

Can anybody me with this? ? (picture included.)

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?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
