These science flashcards have been created by expert tutors alongside student feedback and experienced content developers to provide the very best revision cards. They are on narrow topics in order to practise a single formula or idea, such as one half, m, v, squared, comma, start text, density, end text, equals, start fraction, m, divided by, v, end fraction, 2 1 m v 2, density = v m , etc. For example if there is a sample that has a count rate of 100 counts per minute (cpm) and it takes 30 seconds for it to reach a count rate of __50 cpm __then 30s is the half life for the sample.
2 G → 1 G → 0.5 G → 0.25 G.
