Unless otherwise stated, enter your answers to at least three significant figures.

A student performed an experiment using the same set up as the one used in the lab "Pendulum." The sample data is provided in the table below.

Length, m Period, s
0.80 2.06
0.60 1.76
0.40 1.47
0.70 1.98
0.50 1.66

Copy this data into Graphical Analysis and use it to make a period vs. square root length graph to determine the gravitational acceleration and its error. Make a print screen of your graph and attach it as a file. (Submit a file with a maximum size of 10 MB.)

What is the gravitational acceleration, g?

What is the error, Δg?

Report the results above with the correct number of significant figures.

Use the values for the length, period, and the correctly rounded value of g to calculate the mass of the planet. (Assume its radius to be 6.371 ✕ 106 m.)
