An article discusses the calibration ota radiometer. Several measurements were made on the electromotive force readings of the radiometer [in l.roltsj and the radiation ux {in kilowatts per square meter]- The results {read from a graph} are presented in the following table- m Signal output m Compute the leastsquares line for predicting heat flux from the signal output. Round the answers to three decimal places. y=--o+ox
