Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

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^โ2m on an edge at the ocean's surface, decrease by 7.5 x 10โ10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^โ2, delta v=7.5x10^โ10. at some point l needs to be cubed. why p is divided by delta v?
