Water falls without splashing at a rate of 0.210 L/s from a height of 3.10 m into a 0.630-kg bucket on a scale. If the bucket is originally empty, what does the scale read 2.40 s after water starts to accumulate in it

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

How is the gravitational force related to the distance between two objects?
