Question

1. Superconducting gravimeters are very sensitive and can measure gravitational changes of about 49/9 = 1.0 x 10-11 a. Jackson is standing behind a hay bale holding the meter when Joseph approaches the hay bale from the other side. How close to Jackson can Joseph get before g changes enough for the meter to detect his presence? [Assume Joseph has a mass of 80 kg and is moving very slowly and smoothly - it takes at least a minute to reach this precision.] b. Jason in a hot air balloon and wants to find his rate of ascent (assume it to be constant). What is minimum change in height the meter can detect?
