Please help me with this

a i. The higher curve is "thick wall" and the lower curve is "thin wall".

a ii. The thicker the wall, the more time it takes to transfer the same amount of heat. Thus, the thick wall would have a less steep drop in temperature as it transferred lesser heat from the room to the surroundings and the thinner wall would have a steeper drop in temperature as it conducted more heat away from the room to the surroundings.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

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.
