# Physics - Data Analaysis - Power Laws

posted by Shaila

In an experiment, two variables quantities 'x' and 'y' were measure. The relation between x and y is thought to be y=ax^(1/2)
x(m)+/- 0.01m y(s) +/- 0.05s
0.10 0.64
0.20 0.90
0.40 1.27
0.80 1.80
1.00 1.90

a) What will you graph in the y- and x- axis in order to obtain a straight line graph?

b) Draw and complete a table which allows you yo plot the graph(what is missing to draw an additional table??)

c) Explain why under certain circumstances the graph may not pass through the origin?
