if you want brainliest answer this pleaseeee

a bacterium has a length of 5.5 10-6 m but seen through a powerful microscope it appears to be 1.2 10-3 m. what is the magnification of the microscope?

a virtual image is produced by a convex mirror that is 1.60 cm from the mirror. if the magnification is 0.20 how far from the mirror is the object?
