The activity of a sample reduces from `A_(0) "to" (A_(0))/(sqrt(3))` in one hour. The activity after f3 hours more will be

After 200 days the activity of a radioactive sample reduces to 8000 dps. After another 100 days the activity reduces to 8000/sqrt(2) dps. It can be said that:

The activity of a radioactive sample goes down to about 6% in a time of 2 hour. The half-life of the sample in minute is about

The activity of a radioactive sample decreases to 1//3 of the original activity, A_(0) in a period of 9 years. After 9 years more, its activity A_(0)//x . Find the value of x .

The activity of a radioactive sample decreases to one tenth of the original activity A_(0) in a period of one year further After further 9 years, its activity will be :

The activity of a radioactive sample initially is 3200 dps and after 8hours activity is 100 dps. What will be the activity after 4.8hr from start in dps?

The activity fo a radioactive sample decrases t 1//3 of the orginal acticity. A_(0) in a period of 9 year. After 9 year more, its activity will be:

The activity of a radioactive element decreases in 10 years to 1/5 of initial activity A_(0) . After further next 10 years, its activity will be

After 225 days the activity of a sample is 4000 decay/s. The activity reduces to 2000 decay/s after another 75 days. The initial activity of the sample is

A small amount of solution containing a radioactive nucleide A""^(x) was administrated into the blood of a patient. The activity of the nucliede id 2xx10""^(3) dps. Its half life is 15 hours. After 5 hours a sample of the blood drawn out from the patient. It,s activity was 16 dpm per mL. In the following graph, binding energy per nucleon is plotted against mass number (a). three elements A_(1),A_(2)and A_(3) are located in the graph. Select the false statement about the graph.
