November 1955 5-a-day
Every sheet in November 1955
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 1955A gas is heated in a sealed rigid container. Explain what happens to the pressure.
- 2nd November 1955A ball decelerates uniformly from 18 m/s to 0 m/s over a distance of 2.7 m while being caught. Using (final velocity)^2 = (initial velocity)^2 + 2 x acceleration x distance, calculate its deceleration.
- 3rd November 1955An X-ray has a wavelength of 1 x 10^-10 m. Calculate its frequency (speed of light = 3 x 10^8 m/s).
- 4th November 1955A satellite in a stable, small-radius, close orbit around the Earth is compared with a satellite in a stable, large-radius, distant orbit. State which of the two satellites has the greater orbital speed.
- 5th November 1955Define an undifferentiated cell.
- 6th November 1955Which tissue transports water and mineral ions from the roots?
- 7th November 1955Give three uses of the glucose produced in photosynthesis.
- 8th November 1955Give one piece of evidence that supports Darwin's theory of evolution by natural selection.
- 9th November 1955A peat bog covered an area of 850 hectares in 2015. By 2025, drainage for farmland had reduced the peat bog to 680 hectares. Calculate the percentage decrease in the area of the peat bog.
- 10th November 1955Explain why steel (an alloy of iron and carbon) is generally harder than pure iron.
- 11th November 1955Why do polymers have higher melting points than small molecules such as methane?
- 12th November 1955Complete: acid + metal carbonate gives ...
- 13th November 1955State the four factors that can increase the rate of a chemical reaction.
- 14th November 1955Name the two methods used to produce ethanol industrially.
- 15th November 1955Explain, in one sentence, why the oceans were able to form only after the early Earth had cooled.
- 16th November 1955By what factor does kinetic energy increase if speed is doubled?

- 21st November 1955State one structure found in a bacterial cell but not in an animal cell.
- 22nd November 1955Describe the positive result of the Biuret test.
- 23rd November 1955What is tested during preclinical testing?
- 24th November 1955State why a reflex action is described as involuntary.
- 25th November 1955A student counts 3, 5, 4 and 8 dandelion plants in four separate 1 m^2 quadrats. Calculate the mean number of dandelions per quadrat.
- 26th November 1955Define a finite resource, giving one example.
- 27th November 1955State one reason why simple covalent substances such as chlorine have low melting points.
- 28th November 1955Why do companies prefer reactions with a high atom economy?
- 29th November 1955On a reaction profile diagram, the reactants are drawn at a higher energy level than the products. State whether the reaction is exothermic or endothermic.
- 30th November 1955State what happens to the boiling point of hydrocarbons as their chain length increases.
