The Calla or Arum lily (Zantedeschia spp.) is produced commercially for its use as a cut floweralso see: http:/en.wikipedia.org/wiki/Zantedeschia
if there is a power cut than they will jam shut and you have to force them open
Each lily flower has one pistil and six stamens. If you are showing a lily in a flower show for design, cut the stamens off so the pollen does not stain. If you are showing the lily as a horticulture specimen, do not cut the stamens off.
when lines of force are cut by a conductor we have
If the doorknob were moved to the middle of the door, it would take twice as much force to open it than if it were at the edge of the door. With the mass of the door being equal. Moment = the force to open the door times the distance to the center of the hinges. If the distance were cut in half it would take twice the force to keep the equation true.
put a plaster over the open cut
To cut open in Greek is cise, like in circumcision
Because the film has almost nothing to do with the book?
Spray cans are highly condensed and if you cut one open, it will explode.
When lines of force are cut by a conductor you have electromagnetic induction. A metallic wire can be used as the conductor.
cut it with knife ir sizors
Cells are not atoms; you can indeed cut them open. This can happen naturally through a variety of processes.
