The atmosphere of mars is mostly (molar mass ) under a pressure of 650 pa, which we shall assume remains constant. in many places the temperature varies from 0°c in summer to ‐100°c in winter. over the course of a martian year, what are the ranges of (a) the rms speeds of the co2 molecules and (b) the density (in mol/m3 ) of the atmosphere?

hi there!

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

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

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.
