Answer 2

Answer:

a) the object and the image are twice the lenght of the object to the mirror

so, the distace between monika and her image is 4m

b). the image form by the plane mirror is equal to the actual object

so, the hight of object is 145 cm itself

c) when she walks a distance of 1 m there will be only 1 m distance between her and the mirror

so, the new distance between monika and her image is 2 m
