Match List I (Quantity) with List II (Units) and select the correct answer using the codes given below the Lists: List I List II I. High speed A) Mach II. Wavelength B) Angstrom III. Pressure C) Pascal IV. Energy D) Joule Codes:
- AI-B, II-A, III-C, IV-D
- BI-A, II-B, III-D, IV-C
- CI-A, II-B, III-C, IV-DCorrect
- DI-B, II-A, III-D, IV-C
Explanation
The correct answer is C because each quantity in List I is correctly matched with its standard unit in List II as follows:
I. High speed is matched with Mach. Mach is a dimensionless unit representing the ratio of the speed of an object to the speed of sound.
II. Wavelength is matched with Angstrom. An Angstrom is a unit of length used to measure very small distances such as the wavelength of light.
III. Pressure is matched with Pascal. The Pascal is the standard SI unit of pressure, defined as one Newton per square meter.
IV. Energy is matched with Joule. The Joule is the standard SI unit of energy, work, or amount of heat.
Matching these pairs leads to the sequence I-A, II-B, III-C, IV-D, which corresponds to option C.
