Pure tone sound waves are sinusoidal oscillations of the density of air. our model of waves on an elastic string (beads and massive strings) suggests that waves of moving matter depend on a restoring force (like a tension) and inertia (like a mass), we expect that the speed of sound in air should depend on the air pressure, p (normally about 100 kpa) and the density of the air, rho (normally about 1 kg/m3).part (a) using dimensional analysis, propose an equation for the speed of sound in air using only the parameters p and p. a 17%
part (b) since our dimensional analysis can't tell us if there are numerical factors like 2 or n in our formula, we can't be sure that it provides a good result. calculate what speed of sound your formula predicts. give your answer in m/s. a 17%
part (c) compare your result from part (b) to the real speed of sound. how well does the formula created by dimensional analysis do?

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

You throw a small rock straight up from the edge of a highway bridge that crosses a river. the rock passes you on its way down, 7.00 s after it was thrown. what is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? ignore air resistance.
