To Choose: The correct option.

Answer to Problem 1P
Option (c) is correct, energy is not the base quantity in the SI system.
Explanation of Solution
Introduction:
A physical quantity is any quantity that can be measured. The magnitude of a physical quantity can be measured using the numerical value of physical quantity and the unit in which that quantity is measured.
The unit can be defined as the definite amount of quantity used for the standard of measurement.
Physical quantities are divided into two categories: base quantities and derived quantities and the units corresponding to these quantities are base units or derived units.
Option (c) is correct, energy is not the base quantity in the SI system as it is derived quantity formed by combining three base quantities, length, mass and time.
Option (a) is incorrect, as mass is the base quantity and its SI unit is kilogram.
Option (b) is incorrect, as the length is the base quantity and its SI unit is meter.
Option (d) is incorrect, as time is the base quantity and its SI unit is second.

- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem.
