Answer 2

Answer:

The height of the image of an object whose height is 1 cm is 10 cm.

Explanation:

Step 1 : Write down the formula for magnification.

Magnification = height of image / height of the object.

Step 2 : Analyze the given components in the question.

From the question we have :

Height of the image = h

Height of the of the object = 1 cm

Magnification = 10

Step 2 : Work out the height of the image from the given formula above.

10 = h/1

h = 1 × 10 = 10 cm

The height of the image is therefore 10 cm
