A string has a linear density of 4.80 10-3 kg/m and is under a tension of 345 N. The string is 1.5 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown below in the drawing. (a) Determine the speed of the traveling wave. m/s (b) Determine the wavelength of the traveling wave. m (c) Determine the frequency of the traveling waves that make up the standing wave.
The body contains many small currents caused by the motion of ions in the organs and cells. Measurements of the magnetic field around the chest due to currents in the heart give values of about 1.0 µG. how large is the current in the heart
A crate with a mass of 171.5 kg is suspended from the end of a uniform boom with a mass of 80.3 kg. The upper end of the boom is supported by a cable attached to the wall and the lower end by a pivot (marked X) on the same wall. compute the tensio..
