Question

4. Assertion: Road accidents occurring due to high speeds are much worse

than accidents due to low speeds of vehicles.

Reason: Momentum of high speed vehicles is more than that of low speed

vehicles.

A.If both assertion and reason are true and reason is the correct explanation of

assertion

B.If both assertion and reason are true but reason is not the correct explanation

of assertion.

C.If assertion is true but reason is false.

D.If both assertion and reason are false.​

Answer 1

Answer:

The road accidents at high speeds involve much larger changes in momentum in much

smaller time. Therefore,forces developed (change in momentum/time) are very huge

resulting in disaster

Answer 2

Answer:

B is the answer..............
