The gravitational acceleration in vacuum varies with latitude, elevation, and local inhomogeneities in the earth's crust. Use the following equation to find g in Lawrence based on a latitude of λ=38°57' ±3' and an elevation of H=259±10m. Calculate the uncertainty using the total difference. g = 9.780556m/s2[1+0.0052885sin2λ-0.0000059sin2(2λ)]-0.0000020s-2H How do you include latitude when it's at three different dimensions? And I know the total difference formula but how would you put it in here exactly? Thank you very much for any help!
