Answer 1

Characteristics of the image formed by a plane mirror are:
$1.$ The image formed is erect and virtual. $\left[1\text{mark}\right]$
$2.$ The image is laterally inverted. $\left[1\text{mark}\right]$
$3.$ The image is of the same size as the object. $\left[1\text{mark}\right]$
$4.$ Distance of the image from the mirror will be the same as the distance of the object from the mirror. $\left[1\text{mark}\right]$
$5.$ If the object moves with a speed $v$ with respect to the mirror, then the image of the object will move with a speed $2v$ with respect to the object. $\left[1\text{mark}\right]$
