Question

Give two examples of non- dimensional quantity.​

Answer 1

Answer:

Physical quantity. Unit

Angular displacement. Radian

Solid angle. Steradians

Atomic mass AMU. = 1.66054 x 10-27kg

Answer 2

Two examples of non-dimensional quantities are angular displacement and solid angle.

• Dimensionless quantities can be defined as those quantities that do not have any physical dimensions.
• Two such dimensionless quantities are angular displacement and solid angle.
• Unit of angular displacement is radian.
• While unit of solid angle is steradians.
• These quantities are obtained by multiplying or dividing other quantities which eventually makes them dimensionless.
