Why is iron significant to understanding how a supernova occurs?
A) Iron cannot release energy either by fission or fusion. B) Iron is the heaviest of all atomic nuclei, and thus no heavier elements can be made. C) Supernovae often leave behind neutron stars, which are made mostly of iron. D) The fusion of iron into uranium is the reaction that drives a supernova explosion.

Suppose you have three identical lightbulbs, some wire, and a battery. You connect one lightbulb to the battery and take note of its brightness. You add a second lightbulb, connecting it in parallel with the previous lightbulbs, and again take note of the brightness. Repeat the process with the third lightbulb, connecting it in parallel with the other two. As the lightbulbs are added, the
individual currents in the lightbulbs (neglect the battery’s internal resistance) 1.increases. 2.decreases. 3.remains the same. 4.Need more information.
Lakes lying in granite basins, such as those in the northeastern U.S., tend to become acidified by acid rain more readily than lakes lying in limestone basins, such as those found in the midwestern U.S. Why is this so?
A) The granite contains acidic minerals that dissolve in the rain water and are added to the lakes. B) Since the acidified water cannot percolate through the granite, the acid in the lakes becomes more concentrated. C) The limestone, which is calcium carbonate, serves to neutralize the acid in the rain. D) There is more acid rain in the northeast than in the midwestern regions of the U.S.
