Aperson stands on a scale in an elevator and has a weight of 850 newtons. if the
reading on the scale changes to 500 newtons, what is occurring?

Elevator is going down.

Explanation:

Given that,

Weight of the person standing in the elevator, w = 850 N

                                                                       mg= 850 N

The reading changes to                     W = 500 N

The W can be expressed as

                                           W = (g±a)m  N

Since the mass is constant, the value of W can be lowered only by the '-a' value.

The acceleration 'a' is negative for a person who is accelerating towards gravity.

Hence, the elevator is going down.                                

its a 5.5 n

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.
