The specific heat of liquid mercury is 140 J/kgC. When 1 kg of solid mercury at its melting point of -39C is placed in a 0.5 kg aluminum calorimeter filled with 1.2 kg of water of temperature 20C, the mercury melts and the final temperature of the combination is 16.5 C. What is latent heat of mercury

i need the answer to this too but idk it ; -;

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.
