Select one or more: a. By taking three measurements at each light intensity, the investigator could identify any result that was not expected and repeat the measurements until the expected result was obtained. b. By taking three measurements at each light intensity, the investigator could eliminate any result that did not support the hypothesis. c. By taking three measurements at each light intensity, the investigator could be more confident in the accuracy of the measurements than if the measurement had been made only once.How can microwave ovens heat food more quickly than conventional ovens?
