Number the statements listed below in the order that they would occur in engine operation. then, label these stages as intake, compression, power, or exhaust. a. the fuel mixture is ignited by the spark plug, and the resulting explosion forces the piston down in the cylinder. b. the piston rises and compresses the fuel mixture in the combustion chamber. c. the exhaust gases left over from the combustion are released from the cylinder. d. a mixture of air and fuel is drawn into the cylinder.

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
