Suppose we consider a large number of continers each containing initially `10000` atoms of a radioactive material with a half life of `1` year. After `1` year.A. all the containers will have 5000 atoms of the material.B. all the containers will contain the same number of atoms of the material but that number will only be approximately 5000C. the containers will in general have different number of the atoms of the material but their average will be close to 5000D. none of containers can have more than 5000 atoms.

1.	Suppose we consider a large number of continers each containing initially `10000` atoms of a radioactive material with a half life of `1` year. After `1` year.A. all the containers will have 5000 atoms of the material.B. all the containers will contain the same number of atoms of the material but that number will only be approximately 5000C. the containers will in general have different number of the atoms of the material but their average will be close to 5000D. none of containers can have more than 5000 atoms.
Answer» Correct Answer - c Since half life of the material is 1 year , therefore , after 1 year, half the number of atoms will decay on an average . The containers will in general have different numbers of the atoms of the material but their average will be close to 5000.

A bone containing `200 g` carbon-14 has `beta`-decay rate of `375` decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to `15` decay per min per gram of carbon and half-life of carbon-14 is `5730 years`.A. 22920 yrB. 11460 yrC. 17190 yrD. None of these
Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
