An aluminum can of mass 200g contains 40g of water, both initially at 15°C. Calculate the total quantity of heat that must to be removed from water and the can for their temperatures to fall to
-5°C. (c of water = 4.2J/gºC; c of aluminum = 0.9 J/g°C)

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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.
