Answer:
The most common source of energy for surface waves is wind. earthquakes. tides. volcanoes.
Explanation:
It's hard to tell how the choices are laid out, and they have no labels.
The parallel circuits are the two circuits in your second picture.
One of them is the one with 3 switches, 2 batteries, and 2 light bulbs.
The other one is in the same picture. It's the one where all the circuit components ... the battery and 3 resistors ... are in the 4 vertical lines.
You can't tell the relative values of I-1 and I-2 from the information given,
but that's not for any super-technical reason.
The reason is because the drawing doesn't show WHERE in the circuit
I-1 and I-2 are measured.
It makes a BIG difference if they're the currents in the resistors, or
the currents in and out of the battery.
-- The currents in and out of the battery are equal.
-- The current through either resistor is less than
the current in or out of the battery.
-- The sum of the currents through both resistors
is equal to the current in or out of the battery.
-- The currents through the two resistors may be equal
or unequal, and either one may be greater or less than
the other. It all depends on the values of the resistors.
