How can this be used to calculate the amount of a radioactive element compared to its original amount?
To calculate the amount of a radioactive element compared to its original amount, you need to use the radioactive decay equation: A = A₀ * e^(-λt), where A is the final amount, A₀ is the initial amount, λ is the decay constant, and t is the time elapsed. By plugging in the values for A₀, t, and λ, you can determine the final amount of the radioactive element.
If Astatine-218 has a half-life of 1.6 s Suppose you have a 1.2-g sample of astatine-218 How much of the sample remains unchanged after 6.4 seconds Explain how you solved the problem?
After 1.6 seconds, 0.6 g astatine-218 remains unchanged. This amount is reduced by half to 0.3 g at 3.2 seconds. It is halved again at 4.8 seconds to 0.15 g, and halved once more to 0.075 g unchanged after a total of 6.4 seconds.
What is the formula for calculating the acceleration of an object when given the initial velocity, final velocity, and time elapsed?
The formula for calculating acceleration is: acceleration (final velocity - initial velocity) / time elapsed.
How many half-lives have elapsed when the amount of a sample's Radioactive isotopes is reduced to 3.125 percent of the original amount in the sample?
The idea is to convert the percent to a fraction (divide it by 100), and then solve the equation: (1/2)^x = (that fraction) (Note: Using "^" for "power".) In the general case, solving this equation requires logarithms. But in this specific case, you can just try out different whole numbers for "x". # 1/2 lives vs fraction 1 0.5 2 0.25 3 0.125 4 0.0625 5 0.03175 6 0.015875 The answer falls between 5 and 6 half lives, closer to 5.
Is the velocity of an object always proportional to elapsed time?
No, the velocity of an object is not always proportional to elapsed time. Velocity is defined as the rate of change of an object's position with respect to time, so it can vary depending on factors like acceleration, deceleration, or changes in direction.
A particular element has a half-life of 27 days After 54 days have elapsed how much of the radioactive material is left?
1/4. After 27 days, half of the material will have decayed. After another 27 days half of the remaining material will have decayed. Half of half is 1/4.
How many of the 120 dice would NOT have decayed?
The answer depends on the rate of decay and the elapsed time.

A particular element has a half life of 27 days after 54 days have elapsed how much of the radioactive material is left?
In one cycle, the material would be reduced to one half of the original, leaving one half of the material. In the second cycle (54/27 = 2), there would be 1/2 of that half, leaving 1/4 of the original material.
What happens to the mass of a radioactive isotope as it decays?
In reality, as the atoms gets decayed it gives out radiations such as alpha, beta and Gama. Alpha is a helium nucleus which is massive and beta is electron but fast moving and Gama is an electromagnetic radiation. So as the atom decays then its mass is likely to be reduced. Rutherford's radioactive law deals with the number of atoms undecayed present at an instant 't' given in the form N = No e-lambda t Here No is the total atoms present both decayed and undecayed in a sample. N is the number undecayed present lambda - the decay constant t - the time elapsed
If a radioactive sample has decayed until only one eighth of the original sample remains unchanged how many half-lives have elapsed?
This depends on the type of material. Uranium-238's half-life is 4,438,000,000 years. But the half-life of a material such as Radon-218 is only 35 ms. There is a great range of half-lives for a wide variety of isotopes, so it is impossible to generalize. If you're asking what a half-life is, it is the amount of time it takes for half of any quantity of a radioactive isotope to decay. So if you had a 10g pile of Uranium-238, after 4,438,000,000 years, only 5g of it would still be Uranium-238. The other half would've decayed.
What is Odayz?
In this folder, you get the newest stuff. Original meaning: zero day elapsed since the stuff released, but it's on the net.
What percent of a sample of As-81 remains un-decayed after 43.3 seconds?
To determine the percent of As-81 that remains un-decayed after 43.3 seconds, you would need to know its half-life. The half-life of As-81 is approximately 46.2 seconds. Given that 43.3 seconds is slightly less than one half-life, you can use the formula for exponential decay: [ N(t) = N_0 \left( \frac{1}{2} \right)^{t/T_{1/2}} ] where ( N_0 ) is the initial quantity, ( t ) is the elapsed time, and ( T_{1/2} ) is the half-life. After 43.3 seconds, about 80% of the original sample of As-81 would remain un-decayed.
What is the meaning of elapsed?
Elapsed means: to slip or pass by: Thirty minutes elapsed before the performance began
What does Elapsed transport time mean?
What does elapsed time meen?
Are the stars visible at 7 pm still at 11 pm in their original position?
No - in the four hours that have elapsed, they will have moved 60 degrees across the sky.
What is 1145pm to 330 elapsed time?
Elapsed time11:45pm to 3:30 am
