Question 1Our neighbouring spiral galaxy in Andromeda is catalogued as ‘M 31’ What does ‘M’ indicate ?
Messier Medium Mercator Magnitude
Question 2‘Z’ is not:
Zeta potential Impedance Atomic number Section modulus
Question 3Which of the following combinations is true about the mass of a body according to Newton? Mass is the quantity of matter contained in a body .Mass is represented by the relation, mass= force/ velocity .Mass is always conserved.Mass of a body is the ratio of its weight to the acceleration due to gravity at a particular place.
I. II, and III only I. III, and IV only I, II, and IV only I, II, III, and IV
Question 4Inertia is the property of a body which preserves its state of rest or uniform motion in a straight line. The following factors tell more about inertia: Greater the mass of a body , greater is its inertia, Greater the inertia of a body, lesser will be the acceleration produced by a given force. The law of inertia is the same as Newton’s first law of motion. Which combination is true ?
I, II, and III I, and II only I, and III only II, and III only
Question 5Two fully blown balloons are suspended as shown in the diagram. A stream of air is passed in between the balloons. What will happen to the balloons?
They will come closer They will go apart There will be no change They will go up
Question 6A cricket ball after being hit by a batsman returns to the ground sometime later after having described a parabolic path. Which of the following factors remains unaltered?
The kinetic energy of the ball The potential energy of the ball The horizontal component of the velocity of the ball The vertical component of the velocity of the ball
Question 7Which of the following is not a vector quantity ?
Retardation Displacement Velocity Time
Question 8Consider the following situations : A car moves with uniform speed on a smooth level road.A body moves with uniform speen in a circular path.A labourer carries bricks on his head from one place to another on a smooth level road. Which combination justifies that the work is being done ?
II only I and II only In all the cases In none of the cases
Question 9From Newton’s laws of motion, one can infer that: Newton’s first law describes the motion of a body free of external forces.Newton’s second law relates force to motion.Newton’s third law is a statement about forces in motion.Newton’s third law leads to the principle of conservation of momentum. Which combination is true ?
I, II and III only I, II and IV only II, III and IV only I, II, III and IV
