An object, 0.04 m high, is placed in front of and at right angles to the axis of a concave
the mirror which has a radius of curvature 0.15 m. If
a real image 0.12 m high is obtained,
determine by scale drawing or otherwise, the
the distance of the object from the mirror.
How far, and in what direction, must the
the object be moved in order to obtain a virtual
image 0.12 m high.

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
