the bombardment results into a nucleus with greater proton number
it is an induced nuclear reaction
it is a natural radioactive decay
the sum of the final nucleon numbers
Correct answer is B
This is an example of artificial decay.
Induced radioactivity, also called artificial radioactivity or man-made radioactivity, is the process of using radiation to make a previously stable material radioactive.

Calculate the reactance of the inductor in the circuit diagram shown above [\(\pi = \frac{22}{7}\)]
132\(\Omega\)
214\(\Omega\)
264\(\Omega\)
269\(\Omega\)
Correct answer is C
\(X_L = 2 \pi fL = 2 \times \pi \times 60 \times 0.7 = 264\Omega \)
