Section A (28 Marks)

Answerall questions in this section.

1. A student carries out an experiment to investigate the relationship between the mass attached, m and the

oscillation period, T, of a loaded spring oscillating vertically. The arrangement of the apparatus for the

experiment is shown in Diagram 1.1.

The spring is first attached with a load of m = 50g before being set to oscillate vertically. The time for 10

oscillations, t, is taken by using a stopwatch and its period of oscillation, T, and the value of T2, are calculated.

The experiment is repeated with loads of m = 100g, 150g, 200g and 250g. The corresponding stopwatch readings

are shown in Diagrams 1.2. 1.3, 1.4, 1.5 and 1.6.

Diagram 1.2

m = 50g

t = ___________sT = __________s

T2 = __________s

Diagram 1.3

m = 100g

t = ___________sT = __________s

T2 = __________s

Diagram 1.4

m = 150g

t = ___________s

T = __________s

T2 = __________s

Diagram 1.5

m = 200g

t = ___________s

T = __________s

T2 = __________s

Diagram 1.6

m = 250g

t = ___________s

T = __________s

T2 = __________s

Section B (12 Marks)

3. Diagram 3 shows two opaque water tanks, P and Q, containing different amount of water. Two similar objects,

labeled O, are placed at the bottom of each tank as shown.

tank Q can be seen.

Based on the observation of the depth of the water and the positions of the images of the objects:

a) State one suitable inference. [1 mark]

b) State one suitable hypothesis. [1 mark]

c) With the use of apparatus such as tall beaker, pin, water and other apparatus, describe an experiment to

investigate the hypothesis stated in 3 b).

In your description, state clearly the following:

i) Aim of the experiment.

ii) Variables of the experiment.

iii) List of apparatus of the experiment.

iv) Arrangement of the experiment.

v) The procedure of the experiment, which includes the method of controlling the manipulated variable and

the method of measuring the responding variable.

vi) The way you would tabulate the data.

vii) The way you would analyse the data. [10 marks]
