The strict scientific definition of work is
Work = (force) x (distance) .
If you exert a force but not through any distance, then technically,

has been done until you lift that bale a little higher.
Moles x Mol mass = mass.
<span>Having looked it up, the mol.mass of U-238 is 238.03g/mol. </span>
<span>7.50 moles x 238.03g/mol. = 1,785.23g/mol</span>
Because we can tast the the food already and we get hungry.
50% Because there are two sides of the penny so the chances will always be 50/50
