Red
Blue
Green

@A diode contains which of the following?
An anode and a cathode
An anode only
A base, collector and emitter

@Which one of the following is not a part of a transformer?
Relay coil
Primary coil
Laminated core

@Where abouts is charge found on an object?
Only on the outside surface
Only on the inside surface
Equally on the outside and inside

@An electronic component that stores charge is a:
Capacitor
Resistor
Joulemeter

@Three types of potential energy are:
Gravitational, elastic & chemical
Chemical, friction & heat
Elastic, kinetic & gravitational

@An object accelerates from 30 m/s to 50 m/s in twenty seconds. What is the acceleration?
1 m/s
0.4 m/s
2.5 m/s

@When a mass, suspended from a spring, is not moving it is:
In equilibrium
Not being pulled by gravity
Weightless

@The slope of a distance-time graph is a measure of:
Speed
Acceleration
Displacement

@A dam holds back water. How does the thickness of the dam vary from top to bottom?
It gets thicker towards the base
Its wider at the top than at then base
It must have a constant thickness, otherwise it wouldn't be stable

@A turning force depends on two things. These are:
Force and distance from fulcrum
Mass and weight
Gravity and friction

@Which of the following is a vector?
Force
Mass
Temperature

@When you put your hands in front of a fire they feel warm because of:
Radiation
Conduction
Convection

@Liquids cool after evaporation because:
only slower molecules with less energy are left behind
all the molecules left behind speed up
the molecules left behind get smaller

@Which of these is in the correct order of increasing expansion rates?
Solids, Liquids & Gases
Liquids, Gases & Solids
Gases, Solids & Liquids

@Two, thin, tubes are placed in water as shown. After a few days, what will be seen?
#capil
The water in the smaller tube will have risen more than the larger tube
No change
Water in the larger tube will have risen  much more than the smaller one

@If the following were allowed to pass near a charged gold leaf electroscope, which would produce the greatest effect?
Alpha radiation
Beta radiation
Gamma radiation

@What is the unit used to measure mass?
Kilogram
Newton
Weight

@White light, passing through a prism, emerges as colours of the spectrum. This is because:
the colours of the spectrum are slowed down and 'bent' by different amounts
interference effects cause small amounts of white light to change to different colours
the white light causes the prism to produce colours of the spectrum

@What would be a typical wavelength for microwaves?
About 10cm
One millionth of a metre
Three hundred metres

@Clear glass is:
Transparent
Opaque
Translucent
