Concept explainers
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.

- In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .arrow_forwardIn general, when a derived unit becomes complicated (involves too many standard units), what is done?arrow_forwardConsider the equation y=mt+b, where the dimension of y is length and the dimension of t is time, and mand bare constants.

- A sidewalk is to be constructed around a swimming pool that measures (10.0 0.1) m by (17.0 0.1) m. If the sidewalk is to measure (1.00 0.01) m wide by (9.0 0.1) cm thick, what volume of concrete is needed and what is the approximate uncertainty of this volume?arrow_forwardRoughly how many heartbeats are there in a lifetime?arrow_forwardOne student uses a meterstick to measure the thickness of a textbook and obtains 4.3 cm 0.1 cm. Other students measure the thickness with vernier calipers and obtain four different measurements: (a) 4.32 cm 0.01 cm. (b) 4.31 cm 0.01 cm, (c) 4.24 cm 0.01 cm, and (d) 4.43 cm 0.01 cm. Which of these four measurements, if any, agree with that obtained by the first student?arrow_forward
