Textbook Question
Chapter 3, Problem 1PLA
Scalars are physical quantities that can be completely specified by their __________.
Expert Solution & Answer
To determine
The scalar quantities are mainly defined by.
Answer to Problem 1PLA
The scalar quantities are specified by their magnitude.
Explanation of Solution
The physical quantities are divided into scalars and vectors. The quantities those posses with magnitude only are known as scalars.
For scalar quantities, they do not have any specific direction and only the value that corresponds to.
Some of the examples of scalar quantities are given by, speed, distance, length, volume, density, energy, mass and so on.
Conclusion:
Therefore, the scalar quantities are specified by their magnitude.
