question: hertz:frequency
choices.label: A B C D
choices.text: farah:capacitance joule:power newton:pressure resistance:ohm
explanation: the unit of "frequency" is "hertz". the unit of "capacitance" is "farah". the unit of "power" is not "joules", it is watts. the unit of energy and work is the "joule". the unit of "pressure" is not "newton", it is pa. the unit of force is "newton". the unit of "resistance" is "ohm", but the order of words is inconsistent with the question.
