In a piece of ancient wood C -14 and C - 12 are present. the ratio of C -14 and C - 12 in this wood at present is `1/8th` part of their ratio in the ancient wood. Half life of `C^14` is 5570Y. What is the age of the wood?

In a piece of ancient wood C-14 and C-12 in this wood at present is 1/8 part of their ratio in the ancient wood. Half-life of C^14 is 5570 y. What is the age of the wood ?

In a business the ratio of the investment period of A, B and C is 5:6:8 and the ratio of their profits is 5:3:12 then the ratio of their capital will be

A piece of wood from an archaeological sample has 5.0 counts min^-1 per gram of C-14, while a fresh sample of wood has a count of 15.0 min^-1 gram^-1 . If half life of C-14 Is 5770 years, the age of the archaeological sample is

A piece of wood was found to have C^(14)/C^(12) ratio 0.7 times that in a living plant.Calculate the period when the plant died. Half-life of C^(14)= 5760 years

The isotopic abundance of C - 12 and C - 14 is 98% and 2% respectively. When would be the number of C - 14 isotope in 12 g carbon sample ?

In the atmosphere, carbon dioxide is found in two forms, i.e., ^12CO_2 and ^14CO_2 . Plants absord CO_2 during photosynthesis in presence of chlorophyll, plants synthesise glucose 6CO_2 +6 H_2O rarr C_6H_12O_6 + 6O_2uarr Half life of ^14CO_2 is 5760 years. The analysis of wooden artifacts for ^14C and ^12C gives useful information for determination of its age. All living organisms, because of their constant exchange of Carbon dioxide with the surroundings have the same ratio of C-14 to C-12, i.e. 1.3xx10^-12 . When an organism dies, the C-14 in it keeps on decaying as follows: 6^14Crarr7^14N+(-1)^0e +Energy Thus, the ratio of C-14 and C-12 decreases with the passage of time. We can measure the proportion of C-14 in the remains of dead organism and determine how long ago it died. The method of carbon dating can be used to date anything made or organic matter, e.g., bone, skeleton, wood, etc. Using carbon dating, materials have been dated to about 50,000 years with accuracy. C-14 exists in atmosphere due to:

A piece of wood from an archeological source shows a C-14 activity which is 60% of the activity found in fresh wood today. The age of archeological sample will be:
