June 2004 - GCSE Science 5-a-day
Every GCSE Science sheet published in June 2004, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in June 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 2004A source has a half-life of 5 days and an initial activity of 1600 Bq. What is its activity after 15 days?
- 2nd June 2004A skateboarder of mass 55 kg moving at 4 m/s collides with and grabs onto a stationary shopping trolley of mass 20 kg, and they move off together. Calculate their combined velocity immediately after the collision.
