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 weenie of throws, modus operandi of rotted and tally of un icky(N) of 100 cubes. Number 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 savor calculation: How to calculate the figure 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 break of the container, the cubes realize the whang 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 o f other which was ignored. over again equal amount of forces was not used in throwing out the cubes as a result it limits the number of decayed and undecayed. feasible ways of correcting the errors: ?The experiment should be carried out on a plain table without any obstacle so ideal result would be gotten. ?When the cubes are thrown and on that intimate is anyone on top of each other it should be re-thrown. ? enough 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 jump from 100 and which slowly decreases. Ad in the experiment, the cubes represents atoms radioactive substances and thence they decrease the activity with snip. There is an inverse relationship amongst the dependent variable and independent variable i.e an exponential sequence. As the quantify is zero, the activity is zero but as time increases from zero to twenty, the activity decrease with respect to...If you want to tote up a full essay, ! order it on our website: OrderCustomPaper.com
