Homework Statement
Solve for g in your area with the correct number of significant figures.
Theta = latitude = 50.7 degrees
h = height = 518. m
Homework Equations
g = 9.80616 - 0.025928 cos2(theta) + .00068 cos^2(2*theta) - 0.000003h
The Attempt at a Solution
Well, I just plugged in the data and calculated it to receive 9.81 m/s^2 which sounds right.
The problem is, our teacher said she is really picky about sig figs, and only 4 students have ever gotten the sig figs right for this question.
I can't decide if the answer should be 3 sig figs, as the data with the lowest sig figs is 3.
Or if it should be 1 sig fig because of the term 0.000003h? Although I do not think you include the expression as a limiting factor for significant figures.
So 9.81 m/s^2 or 10 m/s^ or 1*10 m/s^2?
Any help would be greatly appreciated.
Thanks!
