i have some physics questions. please give me ALL CORRECT ANSWERS. thank you Question: The average power from a sound wave passing through an area of 1.16 m2 at a distance of 4.55 m from a source is 3.63 mW The sound wave is propagating isotropically in three dimensions through a gas with a density of 1.29 kg/m3. The wave has a speed of 330 m/s and a displacement amplitude of 5.39 nm at a distance of 4.55 m from...
The plane sound wave is generated by the source which frequency is v = 400 Hz. The amplitude is 8 mm. Find the displacement and velocity of a point at the distance 3 m from a source when t = 0.5s. Velocity of sound wave is 300m/s, ξ(0,0)-0.

1.) If light spreads out in all directions, as it does from a point source, the intensity at a certain distance from the source depends on the area over which the light is spread Light Light source Sphere a.) For a sphere of radius r, what is the equation for the surface area A? b.) Intensity is calculated by taking the power output of the light source divided by the area over which the light is spread: Where I is...
