Aballoon is released 15 feet away from an observer. the balloon is rising vertically at. a rate of 2 ft/sec and at the same time the wind is carrying it horizontally away from the observer at a rate of 3 ft/sec. at what speed is the angle of inclination of the observer’s line of sight changing 5 seconds after the balloon is released?

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?
