If light causes radiation pressure, what about sound waves?

AI Thread Summary
A small paper boat placed in front of a large subwoofer will likely move away when a loud sine wave is played due to the sound pressure generated by the subwoofer. In a microgravity environment, the boat would also move away from the subwoofer, as it would be floating freely without ground friction. Sound waves do not carry momentum, which means they cannot exert a force to push the paper boat. Different waveforms can produce varying effects on sound perception, but they do not affect the fundamental principle of sound wave behavior in this context. Overall, the experiment highlights the influence of sound pressure on lightweight objects in both gravity and microgravity conditions.

What if I put a light object like a small paper boat in front of a large subwoofer and a loud sine wave was played, will that object move away from the sub woofer?

Will the paper boat move away too if the above experiment was done in microgravity? The purpose of microgravity experiment is to eliminate the ground friction factor because the paper boat will be floating freely in midair.

Does different wave forms produce different effects?

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
