Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
newly started
That would depend on the initial amount of the substance, as well as on its half-life.
a radio active substance has half life of 5 days initial mass of 12kg.how much the original isotope will remain after 10 days?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.
After 6 half lives, the remaining will be (1/2)6 i.e 1/64 th of the initial amount. Hence by percentage it would be 1.5625 %
25 gExplanation:Think about what a nuclear half-liferepresents, i.e. the time needed for an initial sample of a radioactive substance to be halved.
That depends what assumptions you make about what the 5 grams of matter is made of.
The initial atom is transformed in another atom.
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
The initial intent was to develop antidotes to poison gas and radioactive contaminants.
This substance is called "reactant" or "initial product".
A common example of exponential decay is radioactive decay. Radioactive materials, and some other substances, decompose according to a formula for exponential decay.That is, the amount of radioactive material A present at time t is given by the formulaA=A0ektwhere k < 0.A radioactive substance is often described in terms of its half-life, which is the time required for half the material to decompose.
The half-life of radioactive material is useful for radioactive dating. For example, All organisms on earth have a given concentration of carbon-14. Since carbon-14 has a half life of 5700 years, scientists can fairly estimate the lifespan of an organism based on its carbon-14 content. This is done by measuring the amount of carbon-14 left from its (previously calculated in a lab) initial amount. If there is exactly a quarter of the initial amount of carbon-14 left in an organism, then it is safe to assume that the organism is 11400 years old. This is why the half-life of a radioactive material is useful for radioactive dating.
