1. nitrogen and oxygen
en and oxygen in their liquid states have densities only 0.8 and 0.9
water. atmospheric pressure is due primarily to the weight of nitro-
and oxygen gas in the air. if the atmosphere liquefied, would its depth
be greater or less than 10.3 m?

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
