www.cikguwong.blogspot.com Collection of Physics Essays 1. Design of driver head and pile:
Design The mass of the driver head should be big. Driver head should be raised higher before dropping The contact surface between the driver head and pile should be hard.
3. Design of spring in suspension car system:
Reason So that, the driver head will have a high momentum or inertia when falls. Have a higher velocity to increase momentum when it strikes at the pile. To reduce the time of impact so that a large impulsive force is produced
2. Design of more efficient generator:
4. Suitable radioisotope in detecting leakage in underground water pipes:

8. Design of loudspeaker and hall to produce loud and clear sound: Design The loudspeakers are not installed against each other.
Reason To avoid multiple reflections.
Loudspeakers are installed at a far distance from each other.
Use soft board for the wall of hall.
So that the distances of constructive and destructive interferences are bigger. So that the sound output will be loud and clear. To reduce echo of sound waves.
Cover the floor with carpet or use sound proof flooring. Sitting area is arranged in the antinode region only.
To avoid reflection of sound wave from the hard floor. So that louder sound can be heard by audience.
Use high powered loudspeakers.
6. Suitable liquid as coolant in car engine:
9. Modifications to improve the reception television signals:
7. Suitable liquid used in thermometer:
Design Use wave of longer wavelength.
Reason To increase the effect of diffraction.
Set up the transmitter on hill tops. Install a relay transmitter on the hill top to amplify and retransmit the signals Build a taller signal receiver at house.
The signal will not be blocked. To increase the strength of signals
Increase the strength of signals.
Able to receive the signals without disruption. The signals can travel further.
