What percentage of the initial radioactivity of cobalt-60 would be left after being stored for 32 years?
The half life of Cobalt-60 is 5.27 years, so 32 years is almost exactly six half lives. (Which is probably why the question is put this way). Every half life the activity halves, so after six half lives it is reduced by a factor 26, which is 64. Therefore the activity after six half lives is 1/64 of the original level, or 1.56 percent.
What else can I help you with?
Can someone illustrate the formula in Physics of compressed air storage with an example?
The formula for compressed air energy storage is given by E = (P1V1 - P2V2)/(n-1), where E represents the energy stored, P1 and P2 are the initial and final pressures, V1 and V2 are the initial and final volumes, and n is the polytropic index. For example, if air is compressed from 100 psi to 600 psi in a storage tank with initial volume of 1000 cubic feet and final volume of 100 cubic feet, the energy stored can be calculated using the formula.
What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
What energy required for a seedling to push up out of the ground comes from?
The energy required for a seedling to push up out of the ground mainly comes from stored reserves in the seed itself. As the seed absorbs water and nutrients from the soil, it uses this stored energy to fuel the initial growth and emergence of the seedling. This process is known as germination.
What is the initial energy source for weight lifting?
The initial energy source for weight lifting is adenosine triphosphate (ATP), which is stored in muscles and used for quick bursts of energy. As you lift weights, ATP is broken down to provide the energy needed for muscle contractions.
The energy stored in oil and coal is stored as what kind of energy?
The energy stored in oil and coal is stored as chemical energy. This energy is released when the substances are burned or oxidized.
What is the initial condition of the elements capacitor and inductor that have no initial energy stored?
The initial condition of a capacitor that has no energy stored is zero volts. The initial condition of an inductor that has no energy stored is zero amperes.
You nuclear wastes must be stored for centuries to prevent dangerous radioactivity from escaping?
Yes
How is radioactivity stored?
This depends on the amount, specific activity, chemical form, type of emitted radiations.
Does a nuclear generating station make pollution?
No, but the spent fuel must be carefully stored after use because it does contain dangerous radioactivity.
