Q.3	A motor car travels with a speed v1 from A to B and returns back from B to A with a speed v2. What is the average speed of the car during its journey?
	a) (v1 + v2)/2		b) (v1v2)/(v1 + v2)
	c) (2v1v2)/(v1 + v2)		d) √(v1 + v2)

Q.4	Look at the pictures shown below and identify the similarity between them correctly:

	c) Both show rusting.		d) Both show crystallisation.

Q.5	Study the given experimental set up. What will happen to the drop of fluid in the capillary tube over the next few hours?
	a) It will move away from the test tube because of oxygen output by the seeds.		b) It will move towards the test tube because of carbon dioxide intake by the seeds.
	c) It will move towards the test tube because of oxygen intake by the seeds.		d) It will not move, because carbon dioxide intake and oxygen output are equal.
