Given the wave function: y(x, t) = 5sin27(0.2x - 3t); (x = meters, t = sec.): what are the amplitude, frequency, wavelength, angular frequency and phase velocity of the wave? in which direction is it traveling? (note: this wave is not a light wave traveling in a vacuum so va = 3 x 108 is not valid)

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s. t.p.?
