K.C.S.E YEAR 2010 PAPER 2 SECTION A 25 marks Answer ALL the questions in this section in the spaces provided. 1. Figure 1, shows a ray of light incident on a plane mirror at O. The mirror is then rotated anticlockwise about O from position M to position M2 through an angle of 10 . The final reflected rayisOC. Determine the angle of deviation BOC. 2. Figure 2 a , shows a magnetic compass placed under a horizontal wire XY A large current is passed from X to Y. Draw the final position of the magnetic compass needle in figure 3. Figure 3, shows a diagram of a current-carrying wire wound on a U-shaped soft iron Draw the magnetic field pattern around P and Q. 4. A positively charged sphere is suspended by an insulating thread. A negatively charged conductor is suspended near it. The conductor is first attracted, after touching the sphere it is repelled. Explain this observation. 5. Figure 4, shows a bright electric lamp placed behind a screen which has a hole covered with a wire gauze. A concave mirror of focal length 25cm is placed in front of the screen. The position of the mirror is adjusted until a sharp image of the gauze is formed on the screen. For More Free KCSE past papers visit www.freekcsepastpapers.comDetermine the distance between the mirror and the screen. 6 Explain why electric power is transmitted over long distances at high voltages. 7. Figure 5, shows how the displacement of a point varies with time as a wave passes it. On the same diagram, draw a wave which passes the point with half the amplitude and twice the frequency of the one shown. 8. A water wave of wavelength 18 mm is incident on a boundary of shallow water at right angles. If the wavelength in the shallow end is 14.4 mm, determine the refractive index of water for a wave moving from the deep to the shallow end. 9. The initial mass of a radioactive substance is 20g. The substance has a half-life of 5 years. Determine the mass remaining after 20 years. 10. A current I flowing through a wire of resistance R was increased seven times. Determine the factor by which the rate of heat production was increased. 11 Figure 6, shows a horizontal conductor in a magnetic field parallel to the plane of the paper.

A hig resistance voltmeter is connected across the cell. 3 Figure 13 The voltmeter reads 1.5V with the switch open and 1.2V with the switch closed. I State the electromotive force of the cell. Ii Determine the current through the 3Q resistor when the switch is closed. Iii Determine the internal resistance of the cell. C i Another resistor R is connected in series with the 3Q resistor so that a current of 0.15A flows when the switch is closed. Determine the resistance of R. 18. Figure 14a, is a diagram of a cathode ray tube. M and N are parallel vertical plates. A When switch S is open, a spot is seen at the centre of the screen as shown in figure 14 b . I State what happens to the spot when S is closed. Ii State what would happen to the spot if the potential difference across MN is increased. Iii State what would be seen on the screen if the battery is replaced with an alternating emf of: I a low frequency of about 1 Hz; II a high frequency of about 50Hz. B Explain the process by which electrons are produced at F. c State with a reason how the brightness of the spot can be increased. D The accelerating voltage of the tube is 1000V and the electron current in the beam is 1.5mA. Determine the energy conveyed to the screen per second. 19. A State the property of radiation that determines the number of electrons emitted when a radiation falls on a metal surface.
