with what tension must a rope with length 2.10 mm and mass 0.120 kgkg be stretched for transverse waves of frequency 45.0 hzhz to have a wavelength of 0.790 mm ?

Sagot :

The tension of a rope of length 2.10 mm and mass 0.120 kg which is stretched for transverse waves of frequency 45.0 hzhz to have a wavelength of 0.790 mm is 51.4 N

What is frequency ?

The quantity of waves that pass a set location in a predetermined period of time is known as frequency.

From the given information -

length =2.10 mm

mass = 0.120 kg

frequency = 45.0 Hz

wavelength =  0.790 mm

V  =  sqrt (T/u)

V  =  40 *0.79   =   31.6 m/s

T/u   =  900

Tension  =  900* 0.12/2.1

Tension  = 51.4 N
