1. A student conduct an experiment to find the relationship between length of pendulum, l and period, T. He used five different length of pendulum, 10cm, 20cm, 30cm, 40cm and 50 cm. Time for 20 oscillations, t1 for each length is recorded as 12.7s, 17.3s, 21.9s, 25.0s and 28.1s. The student repeated the experiment and get different result, t2 12.5s, 17.5s, 22.4s, 26.0s, and 28.2s. He find the average of the reading as t and then find the time for one oscillation or Period, T. Tabulate a table consist of l, t1, t2, t, T and T2.

Draw a graph of T2 against l

What is the relationship between T2 and l

2. Table below show the data taken by a student from scientific investigation instrument.Tabulate the data in suitable formJarak, d (meter)Masa, t, (saat)

21.7, 1.6, 1.6

11.1, 1.0, 1.2

32.0, 1.9, 1.9

54.7, 4.8, 4.6

43.7, 3.6, 3.6

3. Draw a graph of current against voltage from this table

Voltage, V/VCurrent, I/A

1.00.14

2.00.28

3.00.42

4.00.56

5.00.78

6.01.02

What is the relationship between I and V?

4. A student conduct an experiment to study the relationship between Pressure, P and volume, V. He used five different value of pressure, P,= 20, 30, 40, 50, 60 (pascal) and get 5 different volume of air, V,= 50, 33, 25, 20, 17 (cm3).

Construct a table consist of P, V, 1/V.

Plot a graph of 1/V against P

What is the relationship between 1/V and P
