Which property is a characteristic of single-slit diffraction but not double-slit diffraction? the central bright band bands are equally spaced bands get thinner farther from the band red light bands are spaced farther from each other than blue light bands

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

Why are graphs useful when interpreting data

The particles that are found in the nucleus of an atom are
