Answer:

-3m+7m = 4m

Explanation:

As he walks south, he is going down 3m (-3m). Then he walks up 7m (+7m).

You subtract the final position from the initial position to get displacement.

7m - 3m = 4m

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

$m=\dfrac{h'}{h}$

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

$m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm$

So, the size off the object is same as that of the size of the image i.e. 10 cm.
