Every sheet in November 1995
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 1995Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.
- 2nd November 1995Calculate the kinetic energy of a 0.5 kg ball moving at 6 m/s.
- 3rd November 1995State the correct SI unit for density.
- 4th November 1995Explain why americium-241, an alpha emitter, is suitable for use in a smoke detector.
- 5th November 1995Explain why ultraviolet radiation can be harmful to human skin.
- 6th November 1995State two ways of inducing a potential difference across a conductor using a magnetic field.
- 7th November 1995Convert 0.02 mm into micrometres (um).

- 9th November 1995Why does a vaccinated person not usually become ill when they meet the pathogen?
- 10th November 1995A ruler is released and falls 20 cm before being caught. Using distance = 0.5 x g x time^2 with g = 9.8 m/s^2, calculate the reaction time, to 3 significant figures.

- 14th November 1995Calculate the concentration in moles per cubic decimetre of a solution containing 0.5 mol in 250 cubic centimetres.
- 15th November 1995State the energy transfer that occurs during an endothermic reaction.
- 16th November 1995Define the term 'hydrocarbon'.
- 17th November 1995A sample produces only one spot when run in three different solvents. What does this suggest about the sample?

- 22nd November 1995A student wraps a coil of insulated wire around an iron nail and connects it to a battery. Name the device this creates, and state one way to increase its magnetic field strength.
- 23rd November 1995Explain why red-shift observations support the idea that the universe is expanding, rather than Earth simply being at the centre of the universe with everything moving away from it.

- 29th November 1995Write the electronic structure of a magnesium atom (12 electrons).
- 30th November 1995A student measures the mass of a beaker of hydrochloric acid and marble chips as they react and finds it falls. Explain why.
