State which of the following statements are true and which are false. Give reasons for your
answers.
a) A very simple circuit consists of a battery connected across a resistor. In this circuit, the
battery and the resistor are both in series and also in parallel.
b) A resistor R and a capacitor C connected in series combine as 1
RC =
1
R +
1
C
c) Natural uranium is not radioactive until it has been processed by enrichment for use in
fission reactors or bombs.
d) Infrared light is more likely to cause electrons to be emitted from a metal than ultraviolet
light.
e) Special and General Relativity effects both matter for the operation of GPS, the former slowing down the clocks on GPS satellites relative to clocks on Earth and the latter speeding
them up.
