A collector of rare items is negotiating with a museum. He wants to sell a spear he claims to have been
used to kill a mammoth over 11,000 years ago. A spear that size would have started with around 4g of
Carbon-14, and the museum tests show it now contains around 2g. How many half-lives have passed since the spear was carved?

Answer:

I'm not sure if you maybe forgot to add in some information but I can give you the equation you will need to solve this..! (just without the bit of infomration you might need)

[tex]2=4(\frac{1}{2})^{\frac{1100}{t}}[/tex]

In this case you'll be solving for t and I can help you with your first step, you'll divide 2 by 4, getting you to:

[tex]\frac{1}{2} =\frac{1}{2}^{\frac{1100}{t}[/tex]

Answer:

1 as 2g is half of 4g
