1. SI Base Unit for Electric Current Answer: Ampere (\text{A}) 2. Fundamental (Base) Physical Quantity Answer: Mass (Velocity, Force, and Work are all derived quantities). 3. Dimensional Formula for Mechanical Energy or Work Answer: M L^2 T^{-2} (derived from \text{Work} = \text{Force} \times \text{Displacement} = (M L T^{-2})(L) = M L^2 T^{-2}). 4. Speed Conversion (72\text{ km/h} to \text{m/s}) Answer: 20\text{ m/s} (Calculation: 72 \times \frac{5}{18} = 20\text{ m/s}) 5. Significant Figures in 0.00450\text{ m} Answer: 3 significant figures (leading zeros are placeholders, while the trailing zero after the decimal is significant). 6. Metric Prefix and Symbol for 10^{-9} Answer: Nano, represented by the symbol \text{n}. 7. Dimensional Check of v = u + at Answer: Dimensionally consistent. Velocity (v and u): [L T^{-1}] Acceleration \times time (at): [L T^{-2}] \times [T] = [L T^{-1}] Since all terms share the exact same dimensions ([L T^{-1}]), the equation is valid. 8. Derived Physical Quantity for \text{kg} \cdot \text{m} / \text{s}^2 Answer: Force (which is measured in Newtons, \text{N}). 9. Scientific Notation for 5,600,000\text{ m} Answer: 5.6 \times 10^6\text{ m} (assuming two significant figures based on the standard presentation, or 5.60 \times 10^6\text{ m} if three are implied). 10. Fundamental Dimensions of Pressure Answer: M L^{-1} T^{-2} (Pressure = \frac{\text{Force}}{\text{Area}} = \frac{M L T^{-2}}{L^2} = M L^{-1} T^{-2})
