If wavelengths of light
from a definite region of the spectrum are engrossed by a material, then the
materials will appear to be the complementary color. If violet light with

Answer:
Energy of the molecules in the solid ground increases.
Explanation:
If the half-life is 5 minutes, then 30 minutes is equivalent to 6 half-lives. So, after six successive half-lives, the 400 mg of the radioisotope would have a mass of 400(0.5)⁶ = 6.25 mg.
Thus, A would be the correct answer choice here.
