Section : 1 – Mathematics



Section : 2 – Science 21. (c) centimetre / hour 22. (a) < 20 Hz 23. (c) Light year is the unit of length, which is defined as the distance travelled by light in one year. 24. (a) Speed = distance/time.

Thus, distance = speed x time = 8 x 2 = 16 km

25. (c) Sound waves cannot travel through vacuum. 26. (b) Speed = distance/time.

Thus, Speed = 10 / 2 = 5 m/s 27. (d) 365 days 28. (d) Rainwater harvesting 29. (b) During night, bats use sound waves to locate objects while flying. 30. (b) Sight, hearing, taste, smell and touch are the different types of senses.

Section : 2 – Science 21. (b) metre / second2 22. (a) Rectilinear propagation 23. (a) angle of incidence (i) = angle of reflection (r) 24. (c) Concave mirrors are used to form real images. 25. (c) Mass is a scalar quantity, which does not have a direction. 26. (c) In birds, sound is produced by syrinx. 27. (c) cm/min is the unit of 28. (d) Sun is a luminous object which produces light of its own. 29. (b) Bending of light ray when it travels from one medium to another medium is called refraction. 30. (c) Rate of change of velocity is called acceleration.

Section : 2 – Science 21. (c) –40

C/5 = (F–32)/9

–40/5 = (F–32)/9

(–40/5) x 9 = F – 32

F = –72 + 32 = –40

22. (c) A wave in which the medium vibrates parallel to the direction of its propagation is called

longitudinal wave. 23. (d) If the frequency of a longitudinal wave is 100 Hz, 100 compressions and 100 rarefactions are

produced in 1 second. That means 1000 compressions and 1000 rarefactions are produced in 10 seconds. 24. (a) Electrostatic force is responsible for the attraction or repulsion of different particles and materials

based on their electrical charges. 25. (b) A voltmeter should be connected to a circuit in Parallel. 26. (c) If a transverse wave produces 2500 crests and 2500 troughs in 0.1 seconds, it has 2500 oscillations in

0.1 seconds. Thus, Frequency = No. of oscillations / time taken = 2500 / 0.1 = 2500 x 10 = 25000 Hz = 25 kHz

27. (d) In land breeze, wind (air) flows from land to sea. Air always flows from high pressure region to low pressure region. Thus, in land breeze, high pressure is created over the land and low pressure is created over the sea.

28. (a) Speed of sound = frequency x wavelength

Thus, 1500 = (10 x 1000) x wavelength Wavelength = 1500 / 10000 = 0.15 m

29. (c) If an astronaut is inside an earth orbiting spacecraft, he feels zero gravity. 30. (d) The boiling point of water in Celsius scale is 100 oC

In Kelvin scale, its value is 273 + 100 = 373 K



31. Phenolphthalein is colourless in acidic medium and pink in basic medium. 32. Milk of magnesia is 2( )Mg OH because of its milk-like appearance. 33. HCl is called stomach acid which is one of the strongest acids. 34. Acid and base react together to form salt and water (Neutralization Reaction) 35. For rusting, the presence of both Air & Oxygen is essential. 36. An acid that does not contain oxygen, as hydrochloric acid, HCl are called Hydracids. 37. Solid Carbon dioxide is also referred as Dry Ice. 38. Physical changes are reversible changes, no new product is formed and often just a change of state. 39. Chemical changes

are not easily reversible, new products are formed, Heat, light or any other radiation (ultraviolet, for example) may be given off or absorbed. Sound may be produced. A change in smell may take place or a new smell may be given off. Colour change may take place. A gas may be formed

40. Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is

the process of applying a protective zinc coating to steel or iron, to prevent rusting

Red litmus turns blue Phenolphthalein turns colourless to pink Methyl orange turns red to yellow Turmeric turns yellow to red

35. Solids have least compressibility among Solids, Liquids and Gases. 36. Matter:

The particles of matter are very small in size The particle of matter attract each other The particles of the matter are moving constantly The particles of matter have space between them

37. Ammonium chloride undergoes sublimation 38. The symbol of silver is Ag. 39. Mercury (Hg) is liquid at room temperature. 40. Solid is the state of matter which has fixed has fixed shape & fixed volume.
