Astudent stands on a bathroom scale in an elevator at rest on the 64th floor of a building. the scale reads 836 n.
a) as the elevator moves up, the scale reading increases to 935 n, then decreases back to 836 n. find the acceleration of the elevator.
b) as the elevator approaches the 74th floor, the scale reading drops as low as 782 n. what is the acceleration of the elevator?

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?
