A person with hypermetropia needs MCQ with Answer and Explanation

Explanation:
Constant velocity ⇒ no change in speed or direction ⇒ acceleration = dv/dt = 0. Newton's first law: zero net force for constant velocity. Memory tip: 'Constant v ⇒ a = 0; changing v ⇒ a ≠ 0'. Basic kinematics concept frequently tested to verify acceleration-velocity relationship understanding.

Explanation:
Outside N to S, inside S to N, forming closed loops.

Explanation:
V = E - Ir, drop across internal resistance.
