A gasoline-powered generator is used to provide lighting for a house.
Which sequence describes the conversions of energy from the generator to the light bulb?
A. Electrical energy, generated as the electrons move through the wire, changes to chemical energy as the gasoline is burned. The chemical energy changes to mechanical energy from the generator which then changes to light energy seen from the light bulb.
B. Mechanical energy from the generator changes to chemical energy from friction between the moving parts in the generator. This chemical energy changes to electrical energy as the electrons move through the wire and is changed to light energy seen from the light bulb.
C. Thermal energy from friction between moving parts in the generator changes to mechanical energy from the generator. The mechanical energy is changed to chemical energy as the gasoline is burned and is changed to the light energy seen from the light bulb.
D. Chemical energy within the gasoline changes to mechanical energy as the generator's parts begin to move. The mechanical energy is changed to electrical energy, generated as the electrons move through the wire, and changes to to light energy seen from the light bulb.

answer: the figure is attached herewith.

step-by-step explanation: we are given to sketch a unit circle and label the terminal points corresponding to

$\theta=\dfrac{\pi}{3},~2\dfrac{\pi}{3},~3\dfrac{\pi}{3},~4\dfrac{\pi}{3},~5\dfrac{\pi}{3}.\\\\\\\rightarrow \theta=60^\circ,12^\circ,180^\circ,240^\circ,300^\circ.$

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
