Electromagnetism – Question 1
The diagram shows the equipment used by a student to investigate the strength of five different electromagnets.
The Eye – Question 1
The diagram shows the cross-section of an eye.
Red Shift – Question 2
The ‘steady state’ theory was once a popular alternative to the ‘big bang’ theory. The ‘steady state’ theory suggested that the universe, although expanding, had no origin and it has always existed. As the universe expands, a small amount of matter is created to keep the universe looking exactly the same all of the time.
Waves – Question 3
(a) The wavelengths of four different types of electromagnetic wave, including visible light waves, are given in the table.
Atoms and Radiation – Question 3
(a) A radioactive source emits alpha (α), beta (β) and gamma (γ) radiation. (i) Which two types of radiation will pass through a sheet of card?
Electrical Appliances – Question 1
The diagram shows the label from a new freezer.
Energy Efficiency – Question 1
(a) The diagram shows the energy transformations in a fuel burning power station.
Atoms & Radiation – Question 2
The pie chart shows the sources of the background radiation and the radiation doses that the average person in the UK is exposed to in one year. Radiation dose is measured in millisieverts (mSv).
Forces and Elasticity – Question 1
A student investigated how the extension of a spring depends on the force applied to the spring. The diagram shows the spring before and after a force had been applied.
