A certain radioactive element has a half life of 3725 years. How much of a 8.03 g sample is left after 2035 years?
Answer:
What is the energy released when 0.520 g are converted to energy? Express your answer in joules. For self-consistent units you must
use kg because 1 J-1 kg m²/s².
40K decays to 40Ar with a half-life of 1.3 billion years. Argon is a gas, so 40Ar escapes into the atmosphere once it forms. Suppose a sample of granite originally contained 20 g of 40K, but it now contains only 5 g. How many half-lives have passed? How old is the rock?
Do the Paramecium show any signs of being electrically charged? If so, do they carry a positive or a negative charge? Explain.
