An old chair of wood show `""_(6)C""^(14)` activity which is 80% of the activity which is 80% of the activity found today. Calculate the age of the old chair of wood.
(`t""_(1//2)of .""_(6)C""^(14)=5770 yr`)?

A piece of wood from an archaeological source shows a .^(14)C activity which is 60% of the activity found in fresh wood today. Calculate the age of the archaeological sample. ( t_(1//2) for .^(14)C = 5570 year)

A piece of wood from an archelogical source shows a .^(14)C activity which is 60% of the activity found in fresh wood today. Caculate the age of the archeologival sample. ( t_(1//2) for .^(14)C = 5570 year)

A piece of wood from an archaeological source has a "^14C activity which ls 60% of the activity found in fresh wood today. Calculate the age of the archaeological sample (the half life period of C-14 is 5770 years).

What is carbon dating ? Explain. In a sample of wood C-14 activity is 10% of the activity found in fresh wood. Calculate the age of wood sample. (t_1/2 for C-14 is 5760 years )

The amount of ._(6)^(14)C isotope in a piece of wood is found to one fourth (1/4) of that present in a fresh piece of wood. Calculate the age of the piece of wood (t_(12) "of "_(6)^(14)C=5770 "years") a) 7999 year b) 11543 year c) 16320 year d) 23080 year

Half - life period of ""^(14)C is 5770 years . If and old wooden toy has 0.25% of activity of ""^(14)C Calculate the age of toy. Fresh wood has 2% activity of ""^(14)C .
