Help !! You are using sonar over a spot in the ocean known to be 91.8 m deep. The system emits a 50.0-kHz pulse into the water. It takes 120.0 ms for the sound to travel to the ocean floor and back to the sonar system. Determine the speed of sound in the ocean and the wavelength of the sonar pulse.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^β2m on an edge at the ocean's surface, decrease by 7.5 x 10β10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^β2, delta v=7.5x10^β10. at some point l needs to be cubed. why p is divided by delta v?
