A0.5 kg block of aluminum (caluminum=900j/kg⋅∘c) is heated to 200∘c. the block is then quickly placed in an insulated tub of cold water at 0∘c (cwater=4186j/kg⋅∘c) and sealed. at equilibrium, the temperature of the water and block are measured to be 20∘c. if the original experiment is repeated with a 1.0 kg aluminum block, what is the final temperature of the water and block? if the original experiment is repeated with a 1.0 kg copper (ccopper=387 j/kg⋅∘c) block, what is the final temperature of the water and block? if the original experiment is repeated but 100 g of the 0∘c water is replaced with 100 g of 0∘c ice, what is the final temperature of the water and block? if the original experiment is repeated but 100 g of the 0∘c water is replaced with only 25 g of 0∘c ice, what is the final temperature of the water and block?

answer: what are you talking about?

explanation:

they should be similar or the same

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. : )
