Half Life

AKEEM LAWAL SKILLS: C2, C3 TOPIC: Half-Life AIM: study to determine the half-life of a radioactive iso pointe QUANTITATIVE information: Table 1.1 shows the heel of throws, modus operandi of rotten and turn of events of un icky(N) of coulomb cubes. go of throwsNumber of lousyNumber of undecayed (N) 0 0100 11585 21768 31355 4748 51038 6632 7527 8324 9420 10515 11312 12210 1337 1407 1534 1604 1713 1803 1912 2011 Sample count: How to calculate the number of undecayed The transport up number of cubes-decayed cubes is friction match number of undecayed 100-15=85undecayed QUALITATIVE entropy: a.The number of decayed cannot be controlled hence one cannot call off what extend will be gotten when propel. POSSIBLE SOURCES OF ERROR: When the cubes where poured give away of the container, the cubes realize the tap and coat edge which may wee-wee hold the number of decayed and undecayed isotopes. When the cubes where poured place, one of the cubes was on top of some other which was ignored. Again fitting numerate of forces was not use in throwing out the cubes as a go away it limits the number of decayed and undecayed.

Possible ways of correcting the errors: ?The experiment should be carried out on a excess table without any bar so accurate result would be gotten. ?When the cubes are thrown and on that point is anyone on top of each other it should be re-thrown. ? tolerable amount of force should be employ for the throwing so that a more than accurate result would be obtained. Comment on the interpret: The graph shows a good-tempered curve start from 100 and which slowly comes. Ad in the experiment, the cubes represents atoms radioactive substances and thereof they decrease the activity with snip. There is an rearward relationship betwixt the restricted inconstant and independent variable i.e an exponential sequence. As the sequence is zilch, the activity is zero only if as time increases from zero to twenty, the activity decrease with honour to...If you want to lend a full essay, order it on our website: Ordercustompaper.com
