A cylinder with a movable piston contains 0.25 mole of monoatomic ideal gas at a pressure of24000 pa and temperature 355k .The ideal gas expands isobarically to twice its original volume and then compressed adiabatically back to its original volumeand finally cooled isochorically to its original pressure. Compute temperature after adiabatic compression

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?

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.
