Opiates such as morphine sulfate stay in the system for about 72  hours. If a person has a high metabolism and is not a regular user  of the drug it could take at little as â¦48 hours for the morphine to  leave the system.
A convex mirror produces a virtual image, because the principle light rays incident on the mirror surface from the object must pass through the focal point on the other side oâ¦f the mirror (virtually), and so the image appears at a depth behind the mirror's surface.
In order to reflect a planar figure one needs the mirror to be a line (axis of reflection or axis of symmetry), while for reflections in the three-dimensional space one would use a plane (the plane of reflection or symmetry) for a mirror.
