Answer 1

Answer #1

Answer -

50% of carbon -14 is 5730 years
A frozon human Mummy, which was discovered now, was 5100 years old.
As 50% of carbon -14 is 5730 years, then 100% of carbon -14 is 5730 × 2 = 11460 years.
So at 5100 years carbon -14 is :-

100% ÷ 11460 × 5100 = 44.50%

100 - 44.50% =55.50%
