What did Britain import in World War 1?
I believe they imported weapons and food products
What approximate amount of the element remains after 3 half-lives have elapsed?
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
What fraction of a radioactive sample remains after one half-life?
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.
How is the half life of an isotope defined?
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.
What percentage of a radioactive element will be left after 1 half-life?
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%
How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
What is the Half life of penicillin?
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.
What is Alli half life?
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.
How much original matter remains after 9 hours if the matter has a half-life of 3 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.
Is the half-life of a chemical element one-half of the amount of a radioactive element to decay?
The half-life is the time that it takes for 1/2 of a material to decay.
How do you get the pistol in Portal?
you can't its a hack for the computer, but if you do have it on the computer open up the console and type in 'sv_cheats 1 (0=off/1=on)' you NEED to have it on first and then you type in 'impulse 101' for all Half Life 2 weapons you cant JUST get the pistol by the way.
What games does the orange box for ps3 have on it?
