Answer:

\Huge \boxed{\mathrm{200 \ N}}

Explanation:

\sf Weight \ (N)= mass \ (kg) \times acceleration \ of \ gravity \ (m/s^2)

W=mg

The mass of the stone is 20 kg.

The acceleration of gravity is approximately 10 m/s².

W=20 \times 10

W=200

The weight of the object is 200 N.

liraira [26]

Answer:

60 000 N

Explanation:

1 pa = 1 N/m^2

you have 300 000 of these   = 300 000 N /m^2

    but only an area of .2 m^2

                    300 000 N / m^2  * .2 m^2 = 60 000 N

Explain why convex mirrors can only produce virtual images. Please use at least 2 content related sentences. (ref: p.471-481)
34kurt

Convex mirrors can only produce virtual images because the focal point and the center of curvature of the convex mirror are imaginary points and that cannot be reached.

<h3>What is virtual image?</h3>

This is referred to the opposite of a real image and cannot be obtained on a screen. It is formed from the  apparent divergent of light rays from a point  and not the actual one which is the major difference it has with a real image.

It is usually produced by a convex mirror because the focal point and the center of curvature of the convex mirror are imaginary points which can't be reached.
