拿A拿到手软for che ,bio, tips 分享

我都说了no  che ,bio,phy了

不过等明天有空的话啦

    楼主可以分享一下吗？我很很很需要呢～

Section A : 1. Type of physical quantity measured by a measuring
instrument, taking reading from a measuring instrument,
how to avoid zero error and ways to increase the acuracy
of a measurement ( Especially for vernier callipers and
micrometer screw gauge )
2. Momentum and impulsive force ( relationship between
time and impulsive force, ways to reduce impulsive force )
3. Bernoulli' s principle ( aerofoil shape , hor air balloon )
4. heat ( gas laws : Boyle's law or pressure law )
5. Electricity : Circuit diagram , emf and internal
resistance )
6. Wave : Diffraction or refraction of sound
7. Electronic : logic gates and transistor circuit
8. Radioactivity : application in industries and medical field
( treatment of cancer / smoke detector )

Essay : Heat : Specific heat capacity ( land breeze or sea breeze )
Design of a microwave oven to cook food /
characteristics of a coolant used in refrigerator, air cond

Light : Relationship between thickness and power of a lens
Advantage of a convex mirror as a road mirror or side
view mirror of a vehicle
Characteristics of a mirror as a road mirror /
microscope/telescope

Electromagnetism : Working principle of a transformer
How to modify a generator into a motor ( or
vice versa ) and ways to improve efficiency
National grid network ( trasmitting wire ) /
design a circuir to charge handphone or
laptop

Electronic : Type of semiconductor
Doping to produce n-type or p-type semiconductor
Characteristics of foreign atoms in doping /
Modification of a deflecting tube or maltese cross
tube into a CRO /
Type of transistor circuit ( the most suitable one
as a fire detector or automatic switch )

phy first another see for next time

记得说谢谢哦
