The parascender releases the rope and initially rises higher. Explain, in terms of the forces acting, why the parascender rises.	The vertical component of the force exerted by the parasail is greater than the weight of the parascender.
Explain what happens to the density of the trapped air when its temperature is increased.	remains the same neither the mass nor the volume have changed
Capacitors have an insulator between their plates. Explain why there is a current in the circuit during the charging process.	Electrons flow in all the wires because they are repelled from negative terminal of power supply to bottom/one plate of the capacitor and they are attracted off the top/other plate towards positive terminal of power supply
At the end of the run, the engine is switched off and parachutes attached to the car slow it down. Explain how the parachutes slow down the car.	Parachute creates friction (which acts in opposite direction to motion)
Explain the difference between conductors and insulators.	Conductors allow charges to move and insulators do not
Explain what a.c. and d.c. mean in terms of current.	a.c. − Current changes direction continuously (1) d.c. − Current is in one direction

Explain the function of the moderator	slows neutrons
In practice the acceleration is not constant. Give a reason for this.	Other forces will act on the plane, mass decrease
State the speed of ultrasonic waves in air	340 m/s
What happens to the lost kinetic energy?	Turns into heat energy
State what is meant by the term voltage.	(The voltage of a supply is a measure of) the energy given to the charges in a circuit.
State how this affects the speed of the motor compared to Circuit 1. Explain your answer	The motor speed will reduce. The (combined) resistance (of the circuit) is now higher/current is lower. Voltage across motor is less Motor has less power
What is the purpose of component X in the circuit?	To act as a switch
What is the purpose of the variable resistor R in this circuit?	The variable resistor is to set the light level at which the transistor will switch on or to set the level at which the buzzer will sound
Light waves are transverse waves. Sound waves are longitudinal waves. Describe each type of wave in terms of vibrations.	With transverse waves the vibrations are at right angles to the direction of travel. With longitudinal waves the vibrations are in the same direction of travel.
State what is meant by a radiation weighting factor.	A measure of the biological effect of a radiation.
Disposal of some types of radioactive waste from nuclear reactors is particularly difficult. Give a reason for this difficulty.	Stays (highly) radioactive for a (very) long time
Another student carries out the same experiment using a flask of larger volume. Explain why this is a better design for the experiment	A flask of larger volume is better because this increases the mass and volume of air and used in the experiment. This should result in a smaller percentage error in the measurements of both mass and volume of the gas. This will in turn reduce the percentage error in the calculated density of air.
Use the kinetic model to explain what happens to the pressure of trapped air if its volume increases.	Pressure is caused by the gas particles exerting a force on the walls of the container. When the volume of the container decreases there is an increase in the collision rate, meaning that more force is exerted on the container walls. This increases the pressure as pressure is a measure of force per unit area (P = F/A).
What change could be made to this circuit to ensure that the same capacitor stores more energy	Increasing the supply voltage would increase the energy storing capacity of the capacitor. This is because the final voltage, across the fully charged capacitor, would be higher.
In a laser the light is produced by stimulated emission of radiation. Explain the term 'stimulated emission' by making reference to the energy levels in atoms	A high voltage or other energy source can be used to pump electrons up into higher energy states. For example, an electron can be pumped up to energy level (E2) and then fall into the metastable state E1, creating what is called an inverted population. A passing photon, having an energy equal to the energy gap E1 to E0 can encourage/stimulate an electron to drop from energy state E1 to E0 with the production of a photon in phase, with the same frequency and travelling parallel to the stimulating photon. Thereafter, photons produced by stimulated emission can cause further stimulated emission. This is the basis for stimulated emission and amplification.
The distance between the screen and the laser is now doubled. State how the radius of the spot now compares with the one shown in the diagram. You must justify your answer	The laser beam is non divergent. It does not spread out. This means the radius of the spot is a constant.
Two 15kg masses, X and Y, shaped as shown, are dropped through the same distance on two identical uncovered concrete pipes. When the masses hit the pipes, the masses are brought to rest in the same time. Which mass causes more damage to a pipe? Explain your answer in terms of pressure	Block X will cause more damage because the force, although the same for each block, is exerted over a smaller area. This results in more pressure applied to the pipe. Pressure = Force/Area
In the circuit above, the 20 ohm resistor is now replaced with a 10 ohm resistor. The intensity of light is unchanged. The following measurements re obtained.S closed =0.011V. S open= 0.508V. Explain why the reading on the voltmeter, when S is closed is smaller than the corresponding reading in part (b)	Decreasing the value of the load resistor will increase the current in the circuit. This will increase the "lost" volts (Vlost=Ir). Voltmeter reading = emf-Vlost This explains the lower reading on the voltmeter when the switch is closed.
Explain why, as angle x is unchanged, it is important to keep the lightmeter at a constant distance from point X for each measurement of intensity.	By keeping the light meter a constant distance from X you are justified in stating that any change in the recorded intensity is a result of changing q. If the distance was altered a change in intensity could be the result of a diverging beam.
Explain what is meant by photoelectric emission from a metal.	Photoelectric emission is the term used to describe the process by which an electron bound in an atom can absorb enough energy from a single photon to escape, or be emitted, from the atom.
Explain why the actual temperature rise of the disc is less than calculated in (b) (i).	energy is lost to the surrounding air

Explain how this circuit works to close the blind.	The resistance of LDR drops (with light level rise) V across R rises until MOSFET switches on the motor
What is the purpose of the variable resistor R?	to set the light level at which the blind closes.
State whether or not the blinds will close when the light level is	Since V< 2·4 V transistor will not switch on so blinds do not shut.
Why does each LED need a resistor in series?	to limit current in/voltage across the LED

One of the uses of UV radiation is a security feature of bank notes. Shining UV radiation on to the bank note causes them to fluoresce (the atoms in the material take in the UV radiation and re-emits it as light which we can see)

Look at how advanced the fluorescing shapes and colours are.

Experiments- Uses of UV to check the authenticity of bank notes

IR cameras are used by the police to track for criminals at night but they are also really useful to the fire brigade at finding people in smoked filled buildings, you can’t hide behind a bin bag and even a hand print can leave a “heat print”.

You can’t hide in a bin bag if someone has the IR camera on you!

Did you know you can be on the radio? Not very musical but it can drown out Radio Scotland.

Do try this at home, use cheese marshmallows or chocolate but you need to take the turntable out and DON’T put things on a metal tray!

The electromagnetic (em) spectrum is a collection of transverse waves that all travel at the same speed in air, the speed of light, 300 000 000 m/s. (equivalent to 7.5 times round the Earth every second)

One of the waves is VISIBLE LIGHT

Others are RADIO & TV, MICROWAVE.

The others are INFRA-RED, ULTRA VIOLET, X-RAYS, GAMMA WAVES.

The only difference between each of these waves is their wavelength or frequency. They all fit the formula

Speed= frequency × wavelength

v=f λ

The order is important and to remember it use the following rhyme!

Randy Radio & TV

Monkeys Microwaves

Invade Infrared

Venezuela Visible

Using Ultraviolet

Xylophone X-rays

Gunships Gamma

Period, T, is the time for one wave to pass a point and is measured in seconds.

Frequency, f is the number of waves being produced or passing a point per second. Frequency is measured in Hertz (Hz)
