A radioactive substance has has life of 5 days initial mass of 12kg how much the original isotope will remain after 10 days?
After 10 days, 1/2 of the original isotope will remain since its half-life is 5 days. This means 6kg of the original isotope will remain after 1 half-life, which remains the same after 10 days since another half-life has passed.
Why are nights cooler and days warmer?
Nights are cooler because the sun is not shining, so there is no direct heat to warm the air. During the day, sunlight warms the Earth's surface, which then radiates heat into the atmosphere, leading to warmer temperatures.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
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.
The half-life of radon-222 is about four days. After how many days is the amount of radon-222 equal to one-sixteenth of its original amount?
Let's step through the half-life of radon to see how it works. Radon-222 starts at full strength. In four days (its half-life), it is at half strength. In four more days, it is again at half strength (of the half strength) for a total of 1/4 strength. In four more days, it is again half the strength (of the 1/4 strength) for a total of 1/8 strength. In four more days, it is another half life weaker, for a total of 1/16 strength. In 16 days, this isotope of radon has just 1/16th the original radiation.
The half-life of gold-198 is 2.7 days After 5.4 days how much of the original gold-198 remains?
one-quarter After 2.7 Days half of Gold remains. After another 2.7 days half of THAT half remains, which is 25% 5.4
