Consider the following wave function in SI units: ΔP(x, t) = (24.0 / r)sin(1.35r - 2050t)

Explain how this wave function can apply to a wave radiating from a small source, with r being the radial distance from the center of the source to any point outside the source. Give the most detailed description of the wave that you can. Include answers to such questions as the following and give representative values for any quantities that can be evaluated. (Assume that the wave is moving through water at 25°C.)

(c) Find its speed. (m/s)
(d) Find its frequency. (Hz)
(e) Find its wavelength. (m)
(f) Find its power. (W)
(g) Find its intensity at r = 1 m. (W/m^2)v

The center of a long frictionless rod is pivoted at the origin, and the rod is forced to rotate in a vertical plane with constant angular velocity \omega. write down the lagrangian for a bead of mass m threaded on the rod, using r as your generalized coordinate, where r, \phi are the polar coordinates of the bead. (notice that \phi is not an independent variable since it is fixed by the rotation of the rod tobe \phi = \omega * t) solve lagrange's equation for r(t). what happens if the bead is initially at rest at the origin? if it is released from any point ro > 0, show that r(t) eventually grows exponentially. explain your results in terms of the centrifugal force m* \omega ^2 *r.

This event is the result of a sudden vertical offset in the ocean floor and is most often the result of plate movement on the ocean floor. it destroys coast lines and coastal settlements. what is the event called that causes this type of physical damage? a. volcano b. tsunami c. landslide d. liqufication pls !
