Physics

1. Calculate the current in a wire if 1500 C charge is passed through it in 5 minutes. 2. How much current does an electric heater draw from a 220 V line, if the resistance of the heater(when

hot) is 50 Ω? 3. Calculate the resistance of 1 m long copper wire of radius 1mm. Resistivity of copper is 1.72 × 10-8 Ω m. 4. Draw a schematic diagram of a circuit consisting of a battery of 5 V, a 5 ohm resistor, an 8 ohm resistor,

and a 12 ohm resistor, and a plug key, all connected in series. Find the equivalent resistance and total current acrross the combination of resistors.

5. Three resistors of 2 ohm, 3 ohm, and 6 ohm are connected in parallel to a 6 V battery. Find the equivalent resistance and the current across 2 ohm resistor.

6. Three resistors are connected as shown figure. Through the resistor of 5 ohm, a current of 1 A is flowing.

(a) what is the potential diffrence across AC? (b) what is the total resistance?

7. An electic heater draws a current of 5A abd its element has a resistance of 50 ohm. If the heater is switched on for 5 minutes, calculate the energy released in joules.

8. Two bulbs of 100 W each and two cooler of 250 W each, work on an average 6 hours a day. If the energy costs Rs. 1.75. Calculate the monthly bill.

Chemistry

9. Can we stir silver nitrate solution with a copper spoon? Why or why not? 10. What type of reaction represented by the following?

(i) A + B → C (ii)A + BC → AC + B (iii) AB + CD → AD + CB (iv) A → B + C

11. Why do we store silver chloride in dark coloured bottles? 12. Why does blue colour of copper sulphate solution start fading when a zinc rod is dipped in it? 13. Taking a suitable example, explain that oxidation and reduction take place side by side. 14. In the following reaction, name the substance oxidized and the substance reduced:

PbS (s) + 4 H2O2 (aq) → PbSO4 (s) + 4 H2O (I) Which substance acts as oxidizing agent and which one as reducing agent?

15. A silver article generally turns black when kept in the open for a few days. The article when rubbed with toothpaste again starts shining. (a) why do silver articles turn black when kept in the open for a few days? Name the phenomenon involved. (b) name the black substance formed and give its chemical formula.

16. Give two examples from everyday life situations where redox reactions are taken place.

Biology

17. What are outside raw materials used for by an organism? 18. Leaves of a healthy potted plant were coated with vaseline to block the stomata.will the plant remains

healthy for long? State three reasons for your answer. 19. Why is diffusion insufficent to meet the oxygen requirement of multicellular organism like humans? 20. Why is rate of breathing diffrent terrestrial and aquatic animals? 21. What is translocation? Why is it essential for plants? Where in plants are the following synthesised?

(a) sugars (b) hormones 22. Write one function each of the following component of the transport system in human beings:

(a) blood vessels (b) blood platelets (c) lymph (d) heart

23. How are fats digestted in our body? Where does this process take place? 24. Diffrentiate between respiration and breathing. 25. How respiration in plants is diffrent from that in animals?
