There are no working hacks for Roblox.
You don't, Tails isn't playable in Sonic 1 because he wasn't introduced until Sonic 2. I'm sure you can find hacks of Sonic 1 that let you play as Tails though.
Towards the end of the game
hacks use for example modio email me at andregoodarzi@hotmail.com i can answer any questions about black ops 1 black ops 2 and world at war i know all secrets glitches hacks etc...
You can find out in HL2 Ep 1 !SPOILER! She was saved by vortiguants
1/8 amount of the element will reamain. After 1 half-life there is 1/2 left After the 2nd half-life there is 1/2 of 1/2 left which is 1/4 After the 3rd half-life there is 1/2 of 1/4 left which is 1/8
Half of the original sample of a radio isotope remains after a half-life period. After two half-life periods, one-fourth of the radio isotope remains.
A half-life is the time taken for the radioactivity of a material to fall to half its original value. A material can undergo infinite half-lives because each time it falls to half the next half-life falls to half of that half: No half-lives have elapsed when radioactivity is at the original amount; 1/1. 1 half-life is when radioactivity is at 1/2 2 half-lives is when radioactivity is at 1/4. 3 half-lives is when radioactivity is at 1/8. 4 half-lives is when radioactivity is at 1/16. And so on.
Buy Half Life: Source Or Buy Garrysmod a Half-Life 2 Modification and get the addon "Half-Life Rennaisance" Link to Half Life Rennaisance: http://www.garrysmod.org/downloads/?a=view&id=57033 Enjoy!
Half life is pretty much self explanatory in that after they go through 1 half life half of the radioactive decay remains. 1/2 x 1/2 x 1/2 = 1/8 = 0.125 = 12.5% or you can divide 100% by 2, 3 times and you'll get 12.5%
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
The half-life of Alli (orlistat) is around 1 to 2 hours. This means that it takes about 1 to 2 hours for half of the drug to be eliminated from the body.
The half-life of penicillin varies depending on the specific type. For example, the half-life of penicillin G is typically around 30 minutes to 1 hour in the body. Penicillin V, another common type, has a slightly longer half-life of around 1 hour to 1.5 hours.
A half-life means half the original matter decays and is gone after that period. Something with a 3 hour half-live will have only 1/2 its amount left after 3 hours. After 6 hours, only 1/4th is left, and after 9 hours, only 1/8th is left. After one half-life, half is gone. Half is left. After another half-life, half of the remaining half is gone, leaving one quarter left. After the third half-life, half of the quarter is gone and half of that quarter remains, which is an eighth of the original.
Half life is the time for one half of a radioactive substance to decay. In the second half life, another half decays, leaving one quarter. In the third half life, another dalf decays, leaving one eights. And so on and so forth... The equation for the amount left after N half lives is... AN = A0 2(-N/H) ...where H is the half life. In the question asked, if 0.45 of a substance remains after 80 minutes, what is the half life, simply plug in the observations and solve... 0.45 = 2(-80/H) log2(0.45) = log2(2(-80/H)) -1.152 = -80/H H = 69.44 minutes
The half-life is the time that it takes for 1/2 of a material to decay.
