Suggest and explain how to produce a radar that can determine the position of a plane effectively

Explanation:

RADAR is the radio, detection and ranging.

Suppose, you are using the torch to search the object in the dark. The light travels out from the torch and reflects off the object. It bounces back into your eye. Then, brain computes how far away the object is.

In the similar way,  Radar works.  Suppose, an airplane is flying at night through thick fog. In this case, the pilot is unable to see where he is going. He uses the radar. It sends the radio waves only a part of time. The rest time listens out for any reflection of any  nearby objects.

If the reflection is detected then there will be something nearby the plane. It can use the time taken for reflection to figure out how far the object is.

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.
