Question: In one myth, this god fails in his attempts to court his wife until he seduces her in the guise of a cuckoo. He tricks another of his lovers into turning into a fly, then swallows her, only to find out that she was pregnant and that his daughter is causing him a massive headache. In another myth, this god draws lots with his brothers to see who controls the sky, the sea, and the underworld after he castrates and overthrows his father Cronus. For 10 points, name this philandering leader of the Greek gods who is married to the jealous Hera.

Answer: Social Science

Question: Lin and Shu proposed the density-wave theory to explain how the structure of these entities is sustained. The most accurate method for measuring the distances to distant ones uses a relation between their maximum rotational velocity and absolute magnitude, which is known as the Tully-Fisher method. They are generally blue because of their high content of old stars, and one type of them features arms that emanate from each end of a namesake structure. They have discs like the lenticular type, but contain much more angular momentum than the elliptical type. FTP name these galaxies, some of which are barred, including the Milky Way.

Answer: Science

Question: A more advanced form of this quantity is symbolized J and is called the density of this. In one case that density is equal to the permittivity of free space times the time derivative of the electric field. That case was introduced by Maxwell and is called the displacement of this quantity. One law states that its sum about at a junction is zero. It is measured by an ammeter (AM-ee-ter) and is equal to voltage divided by resistance according to Ohm's Law. This quantity is measured in amperes. For 10 points, name this rate of charge, which can be viewed as direct or alternating.
