In which scenario is the least amount of work done on a crate? a force of 120 n moves it 25 m. a force of 115 n moves it 26 m. a force of 130 n moves it 22 m. a force of 125 n moves it 27 m

work done is least for force = 130 N and distance = 22 m

Explanation:

Work done is defined as the product of force applied and the distance traveled by the object.

For force = 120 N and distance = 25 m

Work = 120 x 25 = 3000 J

For force = 115 N and distance = 26 m

Work = 115 x 26 = 2990 J

For force = 130 N and distance = 22 m

Work = 130 x 22 = 2860 J

For force = 125 N and distance = 27 m

Work = 125 x 27 = 3375 J

So, work done is least for force = 130 N and distance = 22 m.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

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.
