what is a term used to describe the electric or magnetic force exerted by oppositely charged objects?

Identify the type of synthetic material used in each object

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

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
