So the half-life of that isotope is one hour. Some isotopes have long half-lives â the half-life of U-234 is 245,000 years. Other isotopes have shorter half-lives. I-131, used in thyroid scans, has a half-life of 8.02 days. Half-Life Calculations. Information on the half-life of an isotope can be used to calculate how much radioactivity of

Starting as a Headcrab at beginning of the game, the player must find a suitable host so that they can become a Zombie. However, if Zombie body is destroyed, the Headcrab will automatically detach the body, much like in Half-Life 2. In Half-Life 2, the Headcrab has a minimum distance for an attack. If the player is touching it, then it will not
Explanation: 1/32 = 1/2^5, so the fossil has aged for 5 half lifes. Assuming the half life is 5,730 years, that's 5 xx 7,730 = 28,650 years old. Answer link. 5 half lifes (half lives?) 1/32 = 1/2^5, so the fossil has aged for 5 half lifes. Assuming the half life is 5,730 years, that's 5 xx 7,730 = 28,650 years old.
To do this, we need to use logarithms: N t = N 0 2 t t1 2. 2 t t1 2 = N 0 N t. log2( N 0 N t) = t t1 2. t1 2 = t log2(N 0 N t) The formula is also frequently expressed using the natural logorithm: t1 2 = t â
ln2 ln(N 0 N t) So, to answer the question, in order to calculate the half life of 14C we would need to know three things: how much we
You know that the half-life of a radioactive nuclide, #t_"1/2"#, tells you the time needed for half of the atoms present in a sample to undergo radioactive decay. In this case, it takes #3.6# days for any sample of this substance to decay to half of its initial mass.
