*Mass Per Unit Length of String The experimental procedure was carried out, and tension versus wavelength squared was plotted. The slope of the graph was found to be 2.4 Nm?, and the frequency was determined to be 40.4 Hz. Determine the mass per unit length of the string, expressing answer in SI units, to 3 significant figures Entering numbers in scientific notation: Example: 1.45 x 10 should be entered as 1.45E-9 Answer:

How can we use the y-intercept and the slope from the graph to
determine Planck's Constant and the work function in the equation
KEmax=hf−ϕ ?
(Note: I know the linearization is showing the y-int. and slope to
be zero because the values are so small, but conceptually how could
we do it?)
