28. Recently, the skeleton of King Richard III was found under a parking lot in England. If tissue samples from the skeleton contain about 93.79% of the carbon-14 expected in living tissue, how many years ago did King Richard III die? The half-life for carbon-14 is 5730 years.
Homework Answers
Decomposition of C-14 follows first order kinetics.
So, using the half life and integrated equation of first order kinetics the time when he died is calculated.

Recently, the skeleton of King Richard III was found under a parking lot in England. If tissue samples from the skeleton, analyzed in 2014, contain about 93.79% of the carbon-14 expected in living tissue, what year did King Richard III die? The half-life for carbon-14 is 5715 years.

An artifact classified as bone, horse, found in a site at Offham, England, is found to have a 14C radioactivity of 0.192 counts per second per gram of carbon. If living carbon-containing objects have an activity of 0.255 counts per second per gram of carbon, estimate the age of the artifact? The half-life of 14C is 5730 years. у

At an archaeological dig, the remains of a saber-tooth tiger are found. In a carbon dating ( 14C has a half-life of 5730 years) test to calculate the age of the cat, a scientist finds that the amount of 14C is about 1/32 the amount of 14C in living animals. How long ago did this saber-tooth tiger die?

The half-life of carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 74% of the carbon-14 expected in living matter when did the tree die? The tree died about years ago (Do not round until the final answer Then round to the nearest whole number.)

Carbon 14 has a half-life of 5.73*10^3 years. C-14 in a piece of living bone has an activity of 14 decays per minute per gram of bone. If a bone found under a parking lot in San Diego has an activity of 3.5 decays per minute per gram of bone, then approximately how long has it been since the bone was alive?

Question 1. (4 marks) Estimating the time of a victim’s death during homicide investigations is a complex problem that cannot be solved by analysising simple equations or functions of one variable. However, many mathematical texts examine time of death estimation based around analysis of Newton’s Law of Cooling. Such analysis is based on implicit simplifying assumptions that: the only dependent variable of interest in determining the time of death is the victim’s body temperature, T(t); the victim’s baseline body temperature...
