The radionuclide `.^(56)Mn` is being produced in a cyclontron at a constant rate `P` by bombarding a manganese target with deutrons. `.^(56)Mn` has a half-life of `2.5 h` and the target contains large numbers of only the stable manganese isotopes `.^(56)Mn`. The reaction that produces `.^(56)Mn` is
`.^(56)Mn +d rarr .^(56)Mn +p`
After being bombarded for a long time, the activity of `.^(56)Mn` becomes constant, equal to `13.86 xx 10^(10) s^(-1)`. (Use `1 n2=0.693`, Avagardo number `=6 xx 10^(2)`, atomic weight of `.^(56)Mn=56 g mol^(-1)`).
At what constant rate P, `.^(56)Mn` nuclei are being produced in the cyclontron during the bombardment?

`2xx10^(11) "nuclei"//s`

`13.86xx10^(10) "nuclei"//s`

`9.6xx10^(10) "nuclei"//s`

The radionuclide .^(56)Mn is being produced in a cyclontron at a constant rate P by bombarding a manganese target with deutrons. .^(56)Mn has a half-life of 2.5 h and the target contains large numbers of only the stable manganese isotopes .^(56)Mn . The reaction that produces .^(56)Mn is .^(56)Mn +d rarr .^(56)Mn +p After being bombarded for a long time, the activity of .^(56)Mn becomes constant, equal to 13.86 xx 10^(10) s^(-1) . (Use 1 n2=0.693 , Avagardo number =6 xx 10^(2) , atomic weight of .^(56)Mn=56 g mol^(-1) ). After a long time bombardment, number .^(56)Mn nuclei present in the target depends upon.

All (i), (ii), and (iii) are correct.

Only (i) and (ii) are correct.

Only (ii) and (iii) are correct.

Only (i) and (iii) are correct.
