BBC - GCSE Bitesize The carbon cycle Im not really sure how to go about solving this problem, any help would be apprecaited. A secondary school revision resource for AQA GCSE Biology about food chains, energy, biomass and the carbon cycle
Carbon-14 Dating - nde- The exponential decay formula is given by: $$m(t) = m_0 e^$$ where $\displaystyle r = \frac$, $h$ = half-life of Carbon-14 = 30$ years, $m_0$ is of the initial mass of the radioactive substance. Carbon-14 Dating. Radio-carbon dating is a method of obtaining age estimates on organic materials. The word "estimates" is used because there is a snificant amount.
Telegraph Promotions So, we have: $\displaystyle r = \frac = \frac = 0.000121$ The mass ratio of Carbon-14 to Carbon-12 is $\displaystyle m_0 = \frac$ (just look this up). Do you love a good deal? Then make the Telegraph Promotions channel your go-to place for special offers and exclusive discounts
Uses and hazards of radiation - BBC 000$ years: $\displaystyle m(12000) = m_0 e^ = 10^e^ \approx 2.34 \times 10^$ I think you can now do the ,000$ year case (just change the value of $t$). Uses and hazards of radiation. Radioactive decay is used in carbon dating, fracking and radiotherapy. Dangers of radiation include causing cancer.
