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.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
