1. The problem statement, all variables and given/known data Solve for g in your area with the correct number of significant figures. Theta = latitude = 50.7 degrees h = height = 518. m 2. Relevant equations g = 9.80616 - 0.025928 cos2(theta) + .00068 cos^2(2*theta) - 0.000003h 3. 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!
