Assertion: Rubber contract on heating.
Reason: In rubber as temperature increases, the amplitude of transverse vibrations increases more than the amplitude of longitudinal vibrations.
Reason: In rubber as temperature increases, the amplitude of transverse vibrations increases more than the amplitude of longitudinal vibrations.
View answer and explanation
Correct option: A
If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
