2. A spherical mirror is to be used in a motion picture projector to form an
inverted, real image 95 times as tall as the picture in a single frame of film.
The image is projected onto a screen 13 m from the mirror. What type of
mirror is required, and how far should it be from the film?

-Spherical Concave mirror

-distance is 0.1368 m

Explanation:

-In physics, magnification is defined as the ratio between the size of the image to the size of the object;

This is also same as;

Given that m=95x, and and the image distance as 13m, the object distance is calculated as:

Hence, the object distance is 0.1368 meters

The image grows bigger when object is moved closer to the mirror, hence , this is a spherical concave mirror

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.
