One half-life is the time required for half of a substance to decay or transform into another substance. The specific duration of a half-life varies depending on the material or isotope in question; for example, the half-life of carbon-14 is about 5,730 years, while that of iodine-131 is approximately 8 days. Therefore, without specifying a particular isotope, one cannot determine a standard duration for a half-life in days.
One and a half days.
Oh, dude, let's break this down like we're solving a mystery. If a peacock and a half lays an egg and a half in one and a half days, that means one peacock lays one egg in one and a half days. So, in three days, two peacocks would lay two eggs. Simple math, my friend.
84 hours
The half life of each radio-isotope is different, so there is no single answer.
Two and a half years typically consist of 912 days. This is calculated by taking 2 years (730 days) and adding half a year (182.5 days), resulting in a total of 912 days. However, if one of the years is a leap year, the total would be 913 days.
If ' L ' is the number of days in one half-life, then the number of half-lives in 32 days is (32 / L) .
54 days is 2x27. After one cycle of a half life (27 days), one-half of the substance would be left. After a second cycle of a half life (27 more days, for a total of 54), one-half of one-half is left, or one-fourth.
The half-life is 4 days. That means half of it will be gone in 4 days, and that leaves half of the original sample. In another 4 days, half of the remaining half will have decayed. And that will leave only 1/4 th of the original sample. That means 3/4 ths of the original sample will have decayed. In 8 days, three fourths of a sample of a radioactive element with a half-life of 4 days will have decayed.
216 Eggs.
one and a half days
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
One and a half days.
The half life of 222Rn, the naturally found isotope of radon, is 3.8235 days.
37 and one half
Oh, dude, let's break this down like we're solving a mystery. If a peacock and a half lays an egg and a half in one and a half days, that means one peacock lays one egg in one and a half days. So, in three days, two peacocks would lay two eggs. Simple math, my friend.
The answer is 2. If after one half-life only half of the element remains, then after another half-life half of what was there only remains. So a half of a half is a quarter (or a fourth). So that's 2 half-lives.
One day and half, is equivalent to 36 hours or 2160 minutes.
