A31.3cm diameter cylinder of nitrogen gas is 70cm long and at 534.48°c. the pressure gauge (as shown) reads 69.9 psi a) how many nitrogen atoms are in the cylinder? b) what is the mass of the nitrogen? c) what is the nitrogen molecule (n2) number density per unit volume? d) what is the gas's mass density?

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.
