KE increased by 100%. Momentum increase percentage: MCQ with Answer and Explanation

KE increased by 100%. Momentum increase percentage:
A. 50%
B. 41.4%
C. 100%
D. 200%
Answer: Option B
Solution (By JKExamLibrary)
KE ∝ p². Double KE ⇒ p_new = √2 p_old ⇒ increase = (√2 - 1)×100% ≈ 41.4%. Memory tip: 'KE ∝ p²; %Δp ≈ ½ %ΔKE for small changes, but use exact for large'. Energy-momentum relation frequently tested in competitive exams.

Question #2 Report Error
A pressure cooker reduces cooking time because
A. Low pressure decreases boiling point
B. It absorbs more heat
C. More water is used
D. High pressure increases boiling point

Correct Answer: Option D


Explanation:
Higher pressure raises boiling point, so water can reach temperatures above 100°C, cooking food faster. At high altitudes, pressure cooker compensates for lower atmospheric pressure.

Question #3 Report Error
The concept of 'Inertia' was first practically developed by which scientist before Newton incorporated it into his First Law?
A. Aristotle
B. Johannes Kepler
C. Galileo Galilei
D. Archimedes

Correct Answer: Option C


Explanation:
Galileo Galilei conducted experiments rolling balls down inclined planes and concluded that an object in motion would continue moving indefinitely on a frictionless surface. This completely challenged Aristotelian mechanics and formulated the concept of inertia, which Isaac Newton later formalized as his First Law of Motion.
