4. A spherical convex mirror has a radius of curvature with a magnitude of 40.0 cm. Determine the position of the virtual image and the magnification for object distances
of
1. 30.0 cm
ii. 60.0 cm
Are the images upright or inverted?

it doesn't. it was imagined up in the middle ages.

c) up is the direction the magnetic force is acting on the charge.
