Barbara places an object in front of a mirror. the mirror produces an image that is inverted, real, and smaller than the object. which kind(s) of mirror could barbara be using? convex, because concave and plane mirrors produce only virtual images concave, because plane and convex mirrors produce only upright virtual images concave or convex, because both types of mirrors produce images that are inverted and real convex or plane, because both types of mirrors produce an image that is smaller than the object

Concave mirror

Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point therefore if the image Barbara is looking at is  inverted, real, and smaller than the object then obviously she is using a concave mirror

B. Concave, because place and convex mirrors produce only upright virtual images.

Explanation:

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
