1. Vertical inversion
2. A real image
3. Lateral inversion
4. An Enlarged image

Option “3” is correct.
The reflection formed by the plane mirror is Lateral inversion.

412. The motion of a freely falling body is an example of ________________________ motion.

1. Uniformly accelerated
2. Non-uniformly accelerated
3. Constant velocity
4. Constant speed

Option “1” is correct.
In general, a uniformly accelerated motion is the one in which the acceleration of the particle throughout the motion is uniform. The motion of a freely falling body is an example of Uniformly accelerated motion.
