Solutions:

S1. Ans.(b)

Sol. Angular momentum is a vector quantity.

S2. Ans.(c)

Sol.When the ice melts to liquid water, the structure collapses and the density of the liquid increases. At temperatures well above freezing, the molecules move faster and get further apart. The density decreases as temperature increases thus, the density of water is a maximum at 4 °C.

S3. Ans.(a)

Sol. Work done due to displacement caused by a force is a scalar quantity.

S4. Ans.(b)

Sol. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

S5. Ans.(b)

Sol. On September 10, 1846, Elias Howe was granted a US patent for his invention of the sewing machine.

S6. Ans.(a)

Sol. The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.

S7. Ans.(a)

Sol. ISRO built India’s first satellite known as Aryabhata.

S8. Ans.(c)

Sol. Acceleration due to gravity, g = (G×M)/R2,
Thus, Acceleration due to gravity at a distance 2R,
g’=(G×M)/(2R+R)2
=(G×M)/9R2
g’ =g/9 ( Since g={G×M}/R2).

S9. Ans.(a)

Sol. Pascal is not unit of Moment of Inertia. Moment of inertia may be expressed in units of kilogram metre squared (kg. m2) in SI units.

S10. Ans.(a)

Sol.Atmospheric pressure is measured by Barometer.
