Packet K: Bonus 13

In the hydraulic analogy, a capacitor is analogous to a hydraulic one of these devices. For 10 points each:
[10h] Give this term, which generically refers to devices that store energy. Compressed nitrogen gas is stored in a “bladder” or separated by a “diaphragm” in a hydropneumatic one of these devices.
ANSWER: accumulators [accept hydraulic accumulators or hydropneumatic accumulators]
[10e] Thermal energy is stored in the form of pressurized steam in a steam accumulator, which are typically used to store thermal energy generated from this source. Photovoltaic cells are used to generate energy from this source.
ANSWER: sunlight [or the sun; or solar power; or solar radiation; prompt on light or photons or radiation by asking “from what source?”]
[10m] Solar collectors generate thermal energy by using mirrors arranged in this shape to focus sunlight onto a single point. The heat equation is a member of a class of partial differential equations named in analogy to this shape.
ANSWER: parabola [or parabolic; accept paraboloids; accept parabolic partial differential equations; accept parabolic troughs or parabolic reflectors]
