Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C14C has decayed to 1/4.00 of the original amount. How long ago was this plant alive?
The uncertainty in the velocity of an electron is 25 × 103 m/s. What is
the uncertainty in its position?
Please give your answer in units of mm, accurate to two decimal places.
Answer:
A particular radioactive material was weighed exactly 1 year ago, showing a mass of 200 g. If the mass was measured today, showing only 1.5 g remaining, calculate the half-life of the radioactive material.Please give your answer in units of days, rounded to the nearest day.
