Physics

The resistance of two things in series is the SUM of their individual resistances.  So the resistance of two bulbs in series is <u><em>double</em></u> the resistance of one bulb.

(If they're in parallel, their combined resistance is <u><em>1/2</em></u> the resistance of one bulb.)

So two bulbs <em>in series</em> is the greater resistance. <em>(a) </em>

Answer;

-Tsunami

Explanation;

-Tsunami  is a series of large ocean waves (or "wave train") of extremely long wavelength and period, usually generated when a gigantic body of water, such as an ocean, is suddenly displaced on a massive scale by an underwater disturbance such as an earthquake occurring on or near the sea floor or a volcanic eruption.

-After a sudden displacement of a large water volume by seismic activity (earthquake), the ocean floor is raised or dropped and large tsunami waves can be formed by gravitational forces.
