1) Half-life of cessium-137 is 30.2 years. If the initial mass of a sample of cessium-137 is 1.000 kg, how much will remain after 151 years? 2) Given that the half-life of carbon-14 is 5,730 years. Consider a sample of fossilized wood that when alive, would have contained 24 gm of carbon-14. It now contains 1.5 gm of carbon-14. How old is the sample?

a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9C temperature increase? (b) Compare your answer to labeling information found on a package of peanuts and comment on whether the values are consistent.

You are working in a biology lab during your summer break. Your supervisor asks you to perform an experiment to find the effective spring constant (in N/m) of a partial molecule of DNA (deoxyribonucleic acid). You perform experiments and find that a single straight portion of a DNA molecule is 2.19 μm long. You then perform an activity that charges the ends of the molecule; each end becomes singly ionized: negative on one end, positive on the other. After the ends are charged, the molecule shrinks by 1.31% of its length. 1.21e-9
