Half Life

AKEEM LAWAL SKILLS: C2, C3 TOPIC: Half-Life AIM: Investigating to determine the half life of a radioactive isotope QUANTITATIVE DATA: Table 1.1 shows the hound dog of throws, modus operandi of rotted and second of un icky(N) of 100 cubes. Number of throwsNumber of disintegrateNumber 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 exemplar calculation: How to calculate the yield of undecayed The tote up number of cubes-decayed cubes is equal number of undecayed 100-15=85undecayed QUALITATIVE DATA: a.The number of decayed cannot be controlled hence one cannot predict what extend result be gotten when thrown. POSSIBLE SOURCES OF ERROR: When the cubes where poured push through of the container, the cubes realize the hit and zinc edge which may have hold the number of decayed and undecayed isotopes. When the cubes where poured out, one of the cubes was on top of other which was ignored. once again equal amount of forces was not used in throwing out the cubes as a result it limits the number of decayed and undecayed.

possible ways of correcting the errors: ?The experiment should be carried out on a plain table without any obstacle so sinless result would be gotten. ?When the cubes are thrown and on that stoppage is anyone on top of each other it should be re-thrown. ? tolerant amount of force should be used for the throwing so that a more accurate result would be obtained. Comment on the graph: The graph shows a smooth curve dinero from 100 and which slowly decreases. Ad in the experiment, the cubes represents ato ms radioactive substances and therefore th! ey decrease the activity with snip. There is an inverse relationship surrounded by the dependent variable and independent variable i.e an exponential sequence. As the condemnation is zero, the activity is zero but as time increases from zero to twenty, the activity decrease with respect to...If you want to supply a full essay, order it on our website: OrderEssay.net
