The amount or quantity.
It is equal to exactly 110.
Y
A micrometer is equal to exactly 1 micrometer.
If you mean "Does the sum of two angles equal exactly 90 degrees?" it is yes.
In radiometric dating, the amount of a certain radioactive isotope in an object is compared with a reference amount. This ratio can then be used to calculate how long this isotope has been decaying in the object since its formation. For example, if you find that the amount of radioactive isotope left is one half of the reference amount, then the amount of time since the formation of the object would be equal to that radioactive isotope's half-life.
No. In two half-lives, a radioactive isotope will decay to one quarter of its original mass. In one half-life, one half of the mass decays. In the next half-life, one half of the remaining mass decays, and so on and so forth. At each half-life point, you would see 0.5, 0.25, 0.125, 0.0625, etc. remaining. The logarithmic equation is... AT = A0 2(-T/H)
NUCLEUS.Atomic energy is produced from changes within nucleus of an atom.
If you take one day equal to 24 hours, then 1 day constitutes 2 Half lives. Mass of isotope left after 12 hours=10/2=5g Mass of isotope left after 2 half lives or 1 day=5/2=2.5g.
The number of neutrons of an isotope is the difference between the mass number of the isotope and the number of protons (equal to atomic number).
Equilibrium.
The bar is a non-SI unit of pressure, defined by the IUPAC as exactly equal to 100,000 Pa. It is about equal to the atmospheric pressure on Earth at sea level.
quantity demanded and quantity supplied are equal
false
The point at which quantity demanded and quantity supplied are equal
It is a state where quantity supplied by seller and quantity demanded by buyers are equal.
A quantity is equal to itself: 24.1 = 24.1
