Part A

(10m)

Part B

1. (a) Time (1m)

(b) 65 x 1000 = 18.06 ms-1

3600 (2m)

(c) n, 10-3, d, 109 (2 corrects – 1m, all corrects – 2m)

2. (a) Increasing velocity (1m)

(b) v = 0.2 = 10 cms-1 (calculation – 1m, 0.02 correct answer with unit – 1m)

(c) u = AB = 10 cms-1 a = v-u v = CD = 1.4 = 70 cms-1 t 0.02 = 70-10 = 750 cms-2

(5-1)(0.02) (calculation – 1m, correct answer with unit – 1m)

3. (a) Ability of measuring instrument to detect small change in physical quantity being measured (1m)

(b) (i) 2.2 A (1m) (ii) The mirror avoid parallax error. During measurement, the eye must be perpendicular

to the scale of the reading and the pointer. Actual reading has been taken when the eye cannot see the image of pointer at the mirror. (3m)

4. Size of capillary Small Increase the sensitivity Type of liquid Mercury/coloured

alcohol opaque

Material of thermometer wall

Glass Transparency/ easy to reading

Shape of thermometer round Easy to see/ reading Thickness of bulb Thin Easy to detect

5. (i) The oscillation period of a pendulum depends on the length of the string // The length of the string affect the oscillation period of a pendulum (1m)

(ii) The longer the length of the string, the longer the period of oscillation (1m)

(iii) Length of string (1m)

(iv) Period of oscillations (1m)
