Acar tire contains 0.0320 m3 of air at a pressure of 2.35 ✕ 105 n/m2 (about 34 psi). how much more internal energy (in j) does this gas have than the same volume has at zero gauge pressure (which is equivalent to normal atmospheric pressure)? (assume the tire pressure of 2.35 ✕ 105 n/m2 is absolute pressure, not gauge pressure. assume for this question that air is monatomic.)

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.

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
