<span>The correct answer is b. Radon. Oxygen, Hyrdrogen, and Boron, are not radioactivel ike Radon and it regenerates quickly meaning that even though it has a short half-life period, it stays for a long time once released. It also has no taste so it's difficult to notice without proper gear because you can't feel it.</span>
density= mass/volume
we need the volume of the metal to find the density, in which case the answer would be 64.2/volume=density
Since 1mL=1cm^3 the wood would sink due to it being more dense. I.e. 0.95>0.88
