May 1956 5-a-day
Every sheet in May 1956
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 1956Explain why ultraviolet radiation can be harmful to human skin.
- 2nd May 1956State two ways of inducing a potential difference across a conductor using a magnetic field.
- 3rd May 1956A student views a red blood cell at a magnification of x2000. The image of the cell measures 20 mm across. Calculate the real width of the cell, giving your answer in micrometres (um).
- 4th May 1956Name the products of protein digestion.
- 5th May 1956State the difference between an antibiotic and a painkiller.
- 6th May 1956A 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.
- 7th May 1956Name the equipment used to measure the abundance of a small plant species within a sample area.
- 8th May 1956State the two main steps used to produce potable water from a fresh water source.
- 9th May 1956State the charge on a calcium ion (Group 2).
- 10th May 1956Convert 250 cubic centimetres into cubic decimetres.
- 11th May 1956A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide. Heating must be continued throughout the reaction for it to keep going. State whether this thermal decomposition reaction is exothermic or endothermic, and explain your reasoning.
- 12th May 1956Define the term 'hydrocarbon'.
- 13th May 1956Write the formula for calculating an Rf value.
- 14th May 1956Readings have a mean of 20.0 cm and a range of 1.0 cm. Calculate the percentage uncertainty.
- 15th May 1956What happens to the total resistance when a second resistor is added in parallel, and why?
- 16th May 1956What happens inside the nucleus when a beta particle is emitted?
- 17th May 1956A shopping trolley has a mass of 25 kg. Calculate its weight, taking g = 9.8 N/kg.
- 18th May 1956A 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.
- 19th May 1956Explain 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.
- 20th May 1956State three factors that increase the rate of diffusion.
- 21st May 1956Name the vector that spreads the protist pathogen that causes malaria.
- 22nd May 1956Explain, in terms of respiration, why a build-up of lactic acid causes muscle fatigue during vigorous exercise.
- 23rd May 1956A man has genotype XY. State his sex, and state which sex chromosomes are found in the sperm cells he produces.
- 24th May 1956What does 'concordant' mean when applied to titres?
- 25th May 1956What did the alpha scattering experiment show that the plum pudding model could not explain?
- 26th May 1956Magnesium is burned in an open crucible and the mass increases. Explain why.
- 27th May 1956In the industrial extraction of aluminium, explain why the aluminium oxide is dissolved in molten cryolite rather than melted on its own.
- 28th May 1956Explain why increasing the surface area of a solid reactant increases the rate of a reaction.
- 29th May 1956Describe the result of the test for carbon dioxide.
- 30th May 1956Give one piece of evidence used to link human activity to recent climate change.
- 31st May 1956Give one advantage and one disadvantage of wind power.
