When a particular wire is vibrating with a frequency of 4.7 hz, a transverse wave of wavelength 71.9 cm is produced. determine the speed of wave pulses along the wire. answer in units of m/s?

The relationship between frequency, wavelength and speed of a wave is given by

where
v is the wave speed
is its wavelength
f is its frequency

for the wave in our problem,  and , so the speed of the wave is (using the previous equation)

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.
