Question 1

If a typical city consumes electrical energy at a rate of how many kilograms of matter would have to be converted entirely into electrical energy in order to keep this city running for
◦ 0.21 kg
◦ 0.19 kg
◦ 0.27 kg
◦ 0.32 kg

Question 2

Monochromatic light is incident on a metal surface, and the ejected electrons give rise to a current in the circuit shown in the figure.  The maximum kinetic energy of the ejected electrons is determined by applying a reverse ('stopping') potential, sufficient to reduce the current in the ammeter to zero. If the intensity of the incident light is increased, how will the required stopping potential change?



◦ It will remain unchanged.
◦ It will decrease.
◦ It will increase.
