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?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
