61. Which one of the following carbon compounds will not give a sooty flame?

Correct Answer: (b) Hexane
Solution:Hexane do not give sooty flame as it is alkane and saturated compound where as Benzene, Naphthalene and Anthracene are aromatic and unsaturated so they give sooty flame.

64. The impulse on a particle due to a force acting on it during a given time interval is equal to the change in its

Correct Answer: (b) momentum
Solution:The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.

65. Which one of the following statements with regard to expansion of materials due to heating is not correct?

Correct Answer: (a) As ice melts, it expands uniformly up to 4°C.
Solution:Most solids expand when heated and contract when cooled. Water/ice is anomalous in that it expands when cooled, at least near its freezing point.

67. Which one of the following is not a form of stored energy?

Correct Answer: (c) Electrical energy
Solution:Nuclear potential and chemical energies implies the stored form of energy. But electrical energy is not a form of stored energy.

68. The motion of a car along a straight path is shown by the following figure

The car starts O and reaches at A, B and C at different instants of time. During its motion from O to C and back to B, the distance covered and the magnitude of the displacement are, respectively

Correct Answer: (d) 85 km and 35 km
Solution:Distance covered by the car = OA + AB + BC + CB = 25 + 10 + 25 + 25 = 85Km
Displacement by the car = OB = 35Km
