Radians are described as appearing in any relationship between angular quantities and:
AChemical quantities
BOptical quantities
CLinear quantities
DThermal quantities
Answer & Solution
Correct answer: C. Linear quantities
1. Radians link the two descriptions of motion.
2. Units of radians are dimensionless.
3. They appear in any relationship between angular and linear quantities.
4. That is why they can be dropped from a final answer.
