(c)assertion is true but reason is false
(d)both asertion and reason are false
(e)assertion is false but reason is true
assertion : the molecules at 0 degree ice and 0 degree water will have the same potential energy
reason : potential energy depends only on the temperature of the system

akhil can you explain ur answers
|

if the net force acting a system is represented by F and its momentum by P , then match the following
COLUMN I COLUMN II
(A) if F is constant (P) p, may change in its direction
(B) if f is changing in magnitude (Q) p must change in its magnitude
(C) if F is changing in direction (R) p may not change in its direction
(D) if F is zero (S) p must not change in its direction

assertion: a race car traveling around a circular track has a non-zero impulse
reason: the impulse is only zero only when there is n net change in momentum
