what is the minimum uncertainty in an electron's velocity (δ������min)(δvmin) if the position is known within 15 å.

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³

Answer it orbits high above earth to gain clearer images of light, it magnifies images relative to the human eye, it records most of the universe as it was in the past, not as it is now;

The density of the block of iron is lees than the density of mercury but the density of the block of iron is greater than the density of water
