For the next experiment, several students placed a marshmallow Peep chick into the microwave. What is the BEST prediction of what will happen to the Peep chick once the microwave is turned on for 15 seconds? A) There is a direct relationship between pressure and volume so the chick will shrink.

B) Whenever there is an increase in temperature there is an increase in volume so the chick expands.

C) The gas molecules inside the marshmallow chick heat up vibrate, increase the pressure outward and the chick expands.

D) Increased pressure due to increased temperature results in a decrease in volume so the marshmallow chick will begin to shrink.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

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. : )
