Many metals can crystallize in more than one type of crystal lattice. D. Metals with a body-centered cubic lattice contain a net of four metal atoms per unit cell. E. A hexagonal close packed structure is not an example of a cubic unit cell.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
