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.
The object is located in front of F for a concave mirror, so the image is upright, virtual and on the opposite side of the mirror. So if the object is positioned below the principal axis, the image is positioned below the principal axis.
