Q12) KL10P3SBQ4 In a morning assembly, two loudspeakers are connected to an amplifier. When the

loudspeakers are located far apart from each other as shown in Diagram 4.1, two students who are

marked with arrows heard the loudest sound.

When the loudspeakers are then adjusted to be closer as shown in Diagram 4.2, another two different

students who are marked with arrows heard the loudest sound.

Q17) PRK11P3SBQ4 Diagram 4.1 and Diagram 4.2 show a cross section of a bicycle dynamo. Each

dynamo has magnet and a coil of insulated copper wire. The output of both bicycle dynamo are

connected to a bicycle lamp. Diagram 4.1 shows the bicycle dynamo has less turns of coil wire than

bicycle dynamo in Diagram 4.2.

When both dynamos are rotated by the bicycle wheel at the same speed, the lamp in Diagram 4.2 lights

up brighter.

Q18) KLT12P3SBQ4Diagram 4.1 and 4.2 show a computer and a hand phone chargers are connected

to power supply 240 V separately. The computer and the handphone charger only need the voltage of 12

V and 9 V respectively.

The step down transformer that is installed in the computer and the hand phone chargers decreased the

voltage supplied from 240 V as output voltage of 12 V and 9 V respectively. The number of turn of the

secondary coil for transformer in the computer is more than in the hand phone charger.

Based on the information and observation:(a) State onesuitable inference. [1 mark]
