The half life of a sample is the time in which the sample decays to half its mass. It depends only on the material(to be exact on its decay constant) and not the quantity .Hence, the half life of the sample remains the same.
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.
The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.
After 2 half lives, 25% of the original radioactive sample remains unchanged. This is because half of the sample decays in each half life, so after 1 half life, 50% has decayed, and after 2 half lives, another 50% has decayed, leaving 25% unchanged.
The half-life of the radioisotope is 20 minutes. This means that in 20 minutes, half of the original sample (20g) remains. Therefore, if a 40g sample becomes 10g after 20 minutes, it has undergone 1 half-life.
Hi, Each half-life means the mass of the sample has decreased by 1/2 its mass. Thus; After 1 half-life, 1/2 the sample has decayed. After 2 half-lives 3/4 of the sample has decayed. Hope this helps.
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
Chawad says... They are directly proportional
Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.
The count rate decreases to 12.5% of the initial value after 3 half-lives, as radioactivity is reduced by half during each half-life.

After 5 half-lives, 3.125% (or 1/2^5) of a radioactive sample remains. Each half-life reduces the sample by half, so after 5 half-lives, there is only a small fraction of the original sample remaining.
Yes,Percy Jackson gets the golden fleece he gets a cyclops as a half brother and at the ending a miracle happens
If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Half of 19 gets you 9 in a half 9.5
it is broken and somebody needs to fix it fast and it is also cut in half
that Pokemon gets half of his HP back What ever Pokemon you give it to, ittle bring them back alive with half HP
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.
