The force that opposes the motion of a falling object in a fluid is known as

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

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
