As you want to get the Karnataka State Board SSLC previous year question papers of Maths and Science so here it is for you: Some content of the file has been given here: 1. Due to heavy traffic near the school the department of traffic police wants to install automatic traffic lights. This can be done by using the Principle of 1 x 10 = 10 a) Raman effect b) Radiography c)Holography d) Photoelectric effect 2. Water is to be sterilized for drinking purpose without using any chemicals this can be done by using a) u v rays b) visible light c) short wave length radio waves d) long wave length Radio waves 3. In a heat engine the linear motion of the Piston is converted into rotation by the component a) spark plug b) Carburettor c) Crank shaft d) Fuel injection pump 4. An engineer wants to design an engine to convert 800KJ of heat into 840KJ of useful mechanical work. The correct statement related to the above engine is that it a) is less efficient b) is more efficient c) cannot be designed d) is 100% efficient 5. An astrophysics Scientist observes that galaxy 'A' is more red shifted than galaxy 'B'. The conclusion that can be drawn from this is that a) the velocity of 'A' is more than 'B' b) the velocity of 'B' is more than 'A' c) both the galaxies have equal velocity d) both the galaxies are at rest. 6. In an nuclear reactor, the number of cadmium rods used are less than the required number. Then one of the possibilities is a) the reactor may explode b) the chain reaction stops c) number of fissions decrease d) the number of neutrons decrease 7.
