5. Why the cell is called the structural and functional unit of life?
6. Gravitational force acts on all objects in proportion to their masses. Why then, a heavy
object does not fall faster than alight object?
7. What are the characteristics of the particles of matter?
8. What is the utility of tissues in multi-cellular organisms?
9. What are the functions of areolar tissue?
10. Differentiate between mass and weight?
11. How do biotic and abiotic factors affect crop production?
12. A solution contains 60g of NaCl in 400g of water. Calculate the concentration in term of
mass by mass percentage of the solution.
13. Write a method to separate a mixture of salt and ammonium chloride?
14. The radius of earth is 6370Km and of mars is 3400 Km. If an object weighs 200N or earth,
what will be its weight on mars. The mass of mars is 0.11 that of earth.
, 15. A 8000 kg engine pulls a train of 5 wagons, each of 2000 kg, along a horizontal track. If the
engine exerts a force of 40000 N and the track offers a friction force of 5000 N, then
calculate:
(a) the net accelerating force;
(b) the acceleration of the train; and
(c) the force of wagon 1 on wagon 2.
1
16. Derive the second equation of motion S = ut + at 2 graphically?
2
17. A solution of H 2 SO4 is labeled 40%. The density of the solution is 1.3gm/l. what is the
concentration of the solution in % (m/v)?
18. Ravi Prasad, a farmer has 25 acres of land. He noticed some infection on the leaves of his
crops. He called his friend Raghav, who advised him to use DDT. However, Ravi preferred to
use dry powder of neem leaves as an insecticide.
Answer the following questions based on the above information:
(a) Why did Ravi Prasad prefer using neem powder?
(b) In your opinion, did he take the right decision?
(c) Write the values associated with decision taken by Ravi Prasad.
19. What is distillation and fractional distillation? What is the basic property that separates the
two methods?
20. Draw a labelled diagram of mitochondria. Write the functions mitochondria.
21. Show diagrammatically how water is purified in the waterworks system and list the
processes involved.
22. Derive expression for force of attraction between two bodies and then define gravitational
constant.
23. Why is crop variety improvement important in cultivation? Describe the important factors
for which variety improvement is done.
24. The driver of train A travelling at a speed of 54 kmh-1 applies brakes and retards the train
uniformly. The train stops in 5 seconds. Another train B is travelling on the parallel with a
speed of 36 kmh-1. Its driver applies the brakes and the train retards uniformly; train B
stops in 10seconds.
Plot speed-time graphs for both the trains on the same axis. Which of the trains travelled
farther after the brakes were applied?
