“a 90.0 kg person rides a spinning amusement park ride that has a radius of 11.5 m. if the person’s tangential speed is 13.2 m/s, what is the magnitude of the centripetal force acting on the person? ”

In what direction does the medium move relative to the direction of the wave? explain.

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?

What causes the formation of ocean currents?
