Nookie1986 [14]

Answer:

$0.033g$

Explanation:

Hello,

In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

$11mg\longrightarrow 1kg\\\\x\ \ \ \ \ \ \longrightarrow 3kg$

Thus, we obtain:

$x=\frac{3kg*11mg}{1kg}\\ \\x=33mg$

That in grams is:

$=33mg*\frac{1g}{1000mg} \\\\=0.033g$

Regards.

The answer is (1) natural transmutation. When Co-60 undergoes beta decay (be it beta positive or beta negative), the product is another element (Fe or Ni). Transmutation is when an element turns into another element via a nuclear process. Since this occurs without the aid of another agent that causes the nuclear change (e.g. a neutron source), it is natural transmutation.
