A 2m string is driven by a 440Hz pulse and resonates in 8loops. the string has a linear density of u=0.050kg/m what is the wavelength of the standing wave?

what is the wave speed in the string?

what is the tension of the string?

what is the fundamental frequency of the string?

suppose you wanted the string to resonate in 3 loops. what frequency should you charge the driver to use?

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^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
