A seated musician plays a G, note at 784 Hz. How much time At does it take for 496 air pressure maxima to pass a stationary listener? At = You would like to express the air pressure oscillations at a point in space in the given form. P (t) = Pmax Cos (Bt) If t is measured in seconds, what value should the quantity B have?

Can i get some help please

For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?
