Hello can someone please answer this How is a conductor different from an insulator?

1: Conductors do not have magnetic fields; insulators do have magnetic fields.
2: In a conductor, electric current can flow freely; in an insulator, it cannot flow freely.
3: In a conductor, electric current cannot flow freely; in an insulator, it can flow freely.
4: Conductors have magnetic fields; insulators do not have magnetic fields.

thermal energy is the answer

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.

the answer is 100. i just did this lesson and got a 100% on it. : )
