MDCAT Physics QUESTION #4397
Question 1
An angular displacement of $90°$ is equal to:
  • One-fourth revolution✔️
  • One-third revolution
  • One-half revolution
  • One complete revolution
Correct Answer Explanation
One complete revolution $= 360°$. Therefore $90° = \dfrac{90}{360} = \dfrac{1}{4}$ of a revolution. Angular displacement of $90°$ equals one-fourth revolution.
