1 SCIENCE (IX) SAMPLE PAPER SECTION A-PHYSICS 1. A body is moving with a uniform speed of 5 m/s. Calculate the amount of force acting on it. 2. Is it possible for an object to have zero velocity but still be accelerated? If yes give an example. 3. During first half of journey a body travels with a speed of 40 Km/h and in the next half it travels with the speed of 20 Km/h. Calculate the average speed of the whole journey. 4. State Newton s 2 nd law of motion and derive its mathematical expression. 5. An object is dropped from the top of a tower reaches the ground in 5 sec. Calculate:- a) The velocity with which it will strike the ground b) The height of the tower. 6. Define relative density. Write its S.I unit. The relative density of silver is 10.8 find the density of silver in S.I unit. 7. State the law of conservation of linear momentum. A girl of mass 30 Kg with a velocity 10 m/s jumps on a stationary car of mass 5 Kg. Find the velocity with which she and cart start moving after she jumps on it. (g=10m/s 2 ) 8. The velocity time graph for a car is given in the adjacent fig. a) What type of motion is covered by the car from (i) A to B (ii) B to C b) Calculate the acceleration of the car from O to A. c) Calculate the distance covered by the car in 2.5 to 7.5 sec. A B 9.Weight of a person on Earth surface is 600 N. What will be the mass of the same person on the surface of the Moon? (g= 10 m/s 2 on earth surface) O C 10.Draw the velocity time graph for the following cases:-

2 a) Uniform motion b) Uniform retardation 11.Give reason for the followings:- a) Dust particles fly off from the carpet when it is beaten with a stick. b) A cricketer lowers his hands while taking a catch. 12.State universal law of gravitation. Write any two importance of it. 13.Derive all three equations of motion. 14.Mass of an object is 80 gm and volume is 40 cm 3 respectively. Will it float or sink? SECTION C-CHEMISTRY 1.How does spreading of wet clothes quicken their drying? Explain. 2.When a solid melts, its temperature remains constant, so where does the heat energy go? What is the name given to this heat? 3.Give reason: (a) Steam produces more severe burns as compared to boiling water. (b) Temperature of a liquid does not change when it boils. 4.(a) Why path of light is not visible in a solution when a beam of light is passed through it? (b) Classify each of the following as solution, colloid or suspension: (i) a mixture whose particles are big enough to scatter to beam of light passing through it. (ii) a mixture whose particles settle down when it is left undisturbed. 5.Differentiate between compound and mixture. (any 2 Points) 6.A solution contains 55 g of sugar dissolved in 670 g of water. Calculate the concentration of this solution? 7.Differentiate between homogeneous and heterogeneous mixtures with example. 8.Air is a mixture or compound? Prove with two points. 9.A gas exerts pressure on the walls of the container. Give reason.

3 10.When the crystal of potassium permagnate is placed at the bottom of a beaker containing water,the water slowly turns purple.why? 11.Convert the following temperatures to the Kelvin scale. (a) 65 0 C (b)323 0 C 12.Give reason to justify that gases have high compressibility. 13.What is sublimation? Explain an experiment to demonstrate the sublimation of ammonium chloride with the help of diagram. 14.The smell of hot sizzling food reaches you several meteres away,but to get the smell from cold food you have to go close. Give reason. 15.Calculate the molecular mass of the following molecules a. H 2CO 3 b. CaCO 3 c.
