Suraj is observing his image in a plane mirror. The distance between the mirror and his image is 6 m. If he moves 2 m towards the mirror, then what will be the distance between Suraj and his image?

Explanation:

In the case of a plane mirror, the distance between the object and the mirror (d1) is same as the distance between image and mirror (d2).

so

if the distance between the mirror and his image is 6 m, then if he moves 2 m towards the mirror the distance between suraj and his image is

(6-2) = 4 m.

Hope it helps :)

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
