Asked in MDCAT Test Series 3 — Rotational and Circular MotionModerate

Statement: A large number of people die every year due to drinking polluted water during the summer.Courses of Action:I. The government should make adequate arrangements to provide safe drinking water to all its citizens.II. The people should be educated about the dangers of drinking polluted water.

Correct answer: D. Both I and II follow

  • A. Only I follows
  • B. Only II follows
  • C. Either I or II follows
  • D. Both I and II follow

Explanation

This problem requires a two-pronged approach. The government has a responsibility to provide a safe water supply (Action I), which is a long-term solution. Simultaneously, educating the public (Action II) empowers them to make safer choices and addresses the immediate risk.

About Rotational and Circular Motion

Angular displacement and angular velocity describe rotation, with angles measured in radians and related to time through angular speed. The connection between angular and linear quantities includes arc length, tangential speed and centripetal acceleration, so circular motion is not confused with motion at constant velocity.
