19M.3.SL.TZ2.bi
An experiment is conducted to determine how the fundamental frequency f of a vibrating wire varies with the tension T in the wire.
The data are shown in the graph, the uncertainty in the tension is not shown.
It is proposed that the frequency of oscillation is given by f2 = kT where k is a constant.
Determine the fundamental SI unit for k.
