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.
1 The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.  The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.
