Question

2)what is the slope of your trendline fit including units? Convert it to standard SI units for comparison with theoretical value above.(show your calculations below. 3)what is the percentage difference between the experimental slope of the graph and it's expected value? Based on the percentage difference that you calculate, does equation (V=sqrt T/mu) appear to be valid?

Explanation / Answer

From theory

we have (v^2 )= 1/mu (T) where v is velocity, mu is linear mass density, T is tension in string

Expected slope is 5077.284 m2/s2/N

2) Slope of trend line from graph is

    4701.8 m2/s2/N

3) PERCENTAGE DIFFERENCE IS

((5077.284 -4701.8)/5077.284) *100

= 7.39 PERCENT

Valid only, this error could be because of missing constant
