The correct Answer is:
To solve the problem of matching the units in Column I with their corresponding values in Column II, we will go through each unit step by step. ### Step-by-Step Solution: 1. **Identify the value of 1 Fermi**: - 1 Fermi is defined as \(10^{-15}\) meters. - Therefore, we match **(A) 1 Fermi** with **(q) \(10^{-15}\) m**. 2. **Identify the value of 1 X-ray unit**: - 1 X-ray unit is defined as \(10^{-13}\) meters. - Therefore, we match **(B) 1 X-ray unit** with **(p) \(10^{-13}\) m**. 3. **Identify the value of 1 Angstrom**: - 1 Angstrom is defined as \(10^{-10}\) meters. - Therefore, we match **(C) 1 Angstrom** with **(r) \(10^{-10}\) m**. 4. **Identify the value of 1 Astronomical Unit (AU)**: - 1 Astronomical Unit is approximately \(1.49 \times 10^{11}\) meters. - Therefore, we match **(D) 1 Astronomical Unit** with **(v) \(1.49 \times 10^{11}\) m**. 5. **Identify the value of 1 Light Year**: - 1 Light Year is defined as \(9.46 \times 10^{15}\) meters. - Therefore, we match **(E) 1 Light Year** with **(s) \(9.46 \times 10^{15}\) m**. 6. **Identify the value of 1 Parsec**: - 1 Parsec is approximately \(3.08 \times 10^{16}\) meters and also equals \(3.26\) Light Years. - Therefore, we match **(F) 1 Parsec** with **(u) \(3.08 \times 10^{16}\) m** and **(t) 3.26 Light Years**. ### Final Matches: - (A) 1 Fermi → (q) \(10^{-15}\) m - (B) 1 X-ray unit → (p) \(10^{-13}\) m - (C) 1 Angstrom → (r) \(10^{-10}\) m - (D) 1 Astronomical Unit → (v) \(1.49 \times 10^{11}\) m - (E) 1 Light Year → (s) \(9.46 \times 10^{15}\) m - (F) 1 Parsec → (u) \(3.08 \times 10^{16}\) m and (t) 3.26 Light Years
