A solid wooden rectangular raft is 4 cm thick , and has a surface area A, which is unknown.it floats in water, submerged to a depth of 3cm. when a man whose mass is 50kg stands on the raft, the upper

Hi help me handle the attached cfd assignment. Make sure to follow instructions.

A spring with spring constant k = 16-N/m and length L = 25.4-cm has masses m = 17-g attached at each end of the spring, and is placed on a frictionless table. Both masses are pulled x = 4.5-cm from eq

How do I solve this problem? A thin pole extends straight up from the bottom of a clear pond 2 m deep. The pole extends 1.2 m above the surface of the water. The sun’s light creates a shadow of the po

If the number of binary bits = 3 and the sampling rate is 2 sample/sec find the signaling rate, number of quantization levels?

hello I need help in solving this the skater part specifically

A simple pendulum oscillates with period TE = 16.1-s on Earth. I take the pendulum to Planet X, and find the oscillation period there to be TX = 42.2-s. Suppose Planet X has the same mass as Earth. Wh

What is the speed of light? How does this relate to relativity?

An object of mass M = 59.2-kg is suspended from the ceiling by a string of length L = 33.6-cm and mass m = 11.4-g. I flick the string so as to set up a pulse that travels from the bottom of the string
