Visit a grocery store and look at the packets and cans of different food items. Read the details given on them ,find and note the energy they contain. Make a list of various food items(at least ten)and the amount of energy they contain in kilojoules per 100gm or 100ml. Also mention whic food contain most energy and which contain least energy.

Ihave no idea how to solve these. plus there's another question that is 2) a 10 kilogram meteorite is collected in space and brought back to earth. it is composed of 1.25 kg of uranium-238 and 8.75 kg of lead-206. how many u-238 half lives have passed? what is the approximate age of the meteorite?
