Because the earth rotates about its axis, a point on the equator experiences a centripetal acceleration of 0.033 7 m/s2, while a point at the poles experiences no centripetal acceleration. (a) show that at the equator the gravitational force on an object must exceed the normal force required to support the object. that is, show that the object's true weight exceeds its apparent weight. (b) what is the apparent weight at the equator and at the poles of a person having a mass of 75.0 kg

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
