<h3><u>Answer;</u></h3>
D. An image that is smaller than the object and is behind the mirror
<h3><u>Explanation;</u></h3>
- Magnification is the ratio of the height of the image to the height of the object.
- When magnification, m, is greater than 1 the image is larger than the object, and when m is less than 1 means the image is smaller than the object.
- If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object.
- Magnification is negative when the image is inverted, therefore a real image.
Ball is thrown at an angle of 20 degree with velocity 18 m/s
so first we will find the two components of the velocity
similarly for other component
now the ball will cover horizontal distance of 30 m till it reach to other player
so here we can use the formula of time
so it will take 1.77 s to reach the other player
