Answer:
The correct answer is - B. It measures the tendency of a radioisotope to decay radioactively.
Explanation:
The half-life of the radioactive sample is the time it takes to decay to its half amount of the unstable nuclei of its initial amount. It is radioactively decays to its half value or in simple words, it takes the time to decay an unstable nuclei to decay to its half value.
It can take milliseconds to million years to disintegrate the different unstable nuclei of a radioactive substance to disintegrate its half amount to a stable substance.

Well it depends how close the places are to the edges of tectonic plates. Also the damage caused from the Earthquakes has to do with how sturdy the buildings are and whether they were built to withhold such strong forces.
Answer:
Explanation:
Aluminium hydroxide () is a base and hydrobromic acid (HBr) is a strong acid.
Hence an acid-base reaction occurs between and HBr

Balanced total ionic equation:
Balanced net ionic equation:
(net ionic equation is written by removing common ions present in both side of total ionic equation)
