An archeologist on a dig finds a fragment of an ancient basket woven from grass. Later, it is determined that the carbon-14 content of the grass in the basket is 9.35 % that of an equal carbon sample from present-day grass.
What is the age of the basket?

An archeologist finds an ancient fire pit containing partially consumed firewood, and the carbon-14 content of the wood is only 10.4 % that of an equal carbon sample from a present-day tree. What is the age in years of the ancient site? Your answer should be in the form of N x 104 years. Enter only the number N with two decimal places, do not enter unit. Carbon-14 has a half-life of 5 730 years

When a plant or an animal dies, its 14C content decreases with a half-life 5730 years. If an archeologist finds an ancient firepit containing partially consumed firewood and the 14C content of the wood is only 15% that of an equal carbon sample from a present-day tree, what is the age of the ancient site?

An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 303 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 14 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
