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 primary mirror is located at the lower end of the telescope tube in a reflector and has its front surface coated with an extremely thin film of metal, such as aluminum. The back of the mirror is usually made of glass, although other materials have been used from time to time.
