1 Summer Holiday Homework Session Grade IX BIOLOGY Project Stem cell and Carbon trading # Students will make model of brain with stem cell and charts on it. # Students will make chart and poster on carbon trading. PHYSICS GEMS AKADEMIAGLOBAL SCHOOL HOLIDAY- HOMEWORK Grade-IX 1 The diagram shows four identical spheres placed between two wooden blocks on a ruler. What is the diameter of one sphere? A 1.0 cm B 2.0 cm C 3.0 cm D 4.0 cm 2 A metal block has the dimensions shown. Its mass is 1000 g.

3The diameter of a copper wire is thought to be approximately 0.3 mm. Which instrument should be used to obtain a more accurate measurement of the diameter of the wire?

2 3The diameter of a copper wire is thought to be approximately 0.3 mm. Which instrument should be used to obtain a more accurate measurement of the diameter of the wire? A measuring tape B metre rule C micrometer D ruler 4 Which is a unit of acceleration? A g / cm3 B m / s C m / s 2 D N / m 5 The diagram shows a cuboid block made from a metal of density 2.5 g / cm 3. What is the mass of the block? A 8.0 g B 16 g C 50 g D 100 g 6 What does the area under a speed-time graph represent? A acceleration B average speed C deceleration D distance travelled

3 7 A car travels 100 km. The journey takes two hours. The highest speed of the car is 80 km / h, and the lowest speed is 40 km / h. What is the average speed for the journey? A 40 km / h B 50 km / h C 60 km / h D 120 km / h 8 The diagram shows a uniform beam being used as a balance. The beam is pivoted at its centre. A 1.0 N weight is attached to one end of the beam. An empty pan weighing 0.2 N is attached to the other end of the beam. How many 0.1 N weights must be placed on the pan in order to balance the beam? A 5 B 8 C 10 D 12 9 The diagrams show four identical objects. Each object is acted on by Which object accelerates to the right, with the smallest acceleration? 10 An object is released from rest and falls to Earth. During its fall, the object is affected by air resistance. The air resistance eventually reaches a constant value. Which description about successive stages of the motion of the object is correct? A constant acceleration, then constant deceleration B constant deceleration, then zero acceleration C decreasing acceleration, then constant deceleration D decreasing acceleration, then zero acceleration

4 11 A concrete post is carried up a very high mountain. At the top of the mountain, the gravitational field is slightly weaker than at the bottom. What is the effect of this weaker field on the mass and on the weight of the post at the top of the mountain? 12 The diagram shows an object moving at a constant speed in a circular path in the directionshown. A force acts on the object to keep it in the circular path. In which labelled direction does this force act, when the object is in the position shown? STRUCTURED 1 A driving instructor gives a student a sudden order to stop the car in the shortest possible time. Fig. 1.1 shows the speed-time graph of the motion of the car from the moment the order is given.

5 (a) The order to stop is given at time t = 0 s. (i) State the speed of the car at t = 0 s. speed =...[1] (ii) Suggest why the car continues to travel at this speed for 0.9 s [1] (b) Calculate (i) the deceleration of the car between t = 0.9 s and t = 4.0 s, =...[2] (ii) the total distance travelled by the car from t = 0 s. distance =...[3]

(c) Describe and explain a danger to a driver of not wearing a safety belt during a sudden stop..........[2] [Total: 9] 2 Fig. 2.1 shows a hammer being used to drive a nail into a piece of wood.

6 (c) Describe and explain a danger to a driver of not wearing a safety belt during a sudden stop [2] [Total: 9] 2 Fig. 2.1 shows a hammer being used to drive a nail into a piece of wood. The mass of the hammer head is 0.15 kg. The speed of the hammer head when it hits the nail is 8.0 m / s. The time for which the hammer head is in contact with the nail is s. The hammer head stops after hitting the nail. (a) Calculate the change in momentum of the hammer head. change in momentum =...[2] (b) State the impulse given to the nail. =...[1] (c) Calculate the average force between the hammer and the nail. average force =...[2] [Total: 5] END
