Choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
(A) Force — this matches (III) newton. One newton is the force that gives a mass of 1 kg an acceleration of 1 m/s2.
(B) Charge — this matches (I) coulomb. One coulomb is the charge carried by a current of 1 ampere in 1 second.
(C) Heat — this matches (IV) joule. Heat is a form of energy, and the SI unit of every form of energy is the joule.
(D) Frequency — this matches (II) hertz. One hertz is one cycle (vibration) per second.
