Q: Which of the following statements about viscosity is true?
Solution: Viscosity is a scalar quantity that measures a fluid's resistance to flow.
Steps: 4
Step 1: Understand what viscosity means. Viscosity is a property of fluids that describes how thick or sticky they are.
Step 2: Recognize that viscosity measures how easily a fluid can flow. A fluid with high viscosity (like honey) flows slowly, while a fluid with low viscosity (like water) flows easily.
Step 3: Note that viscosity is a scalar quantity, which means it has a magnitude but no direction, unlike vector quantities that have both magnitude and direction.
Step 4: Conclude that the statement 'Viscosity is a scalar quantity that measures a fluid's resistance to flow' is true.
