Psubscript"h" - is the static pressure between the level of the highest design point on the floor concerned and the level of the highest design point in the top storey.

Does anybody can help me to define what do we mean by
i. highest design point on the floor and
ii. highest design point in the top storey.

Is kind of confusing.

Here is the question that I am having trouble trying to decipher and solve: Erica and Alicia skate for their college speed-skating team. In the last race, Erica skated the 500-meter race in 61 seconds. The average for this race is 65 seconds with a standard deviation of 4.0 seconds. Alicia skated the 1000-meter race in 134 seconds. The average for this race is 140 seconds with a standard deviation of 10.0 seconds. Find the z-score for each skater. Which skater had the faster time? Justify your answer. Please help me, thanks!!

This includes all 50 states. To be fair, its a trick question so be careful with your answers.

Prof said: No integration or Riemann's sum or rectangles required.
Hint: Imagine a stadium, you have people and you tell them all to sit down so every seat is full and everyone has 1 chair. you know the number of people equals the number of seats, without knowing the numbers of either.

Any help would be lovely, thank you.

Hi guys!
I'm graduating highschool in 07' and my teachers reccomended engineering. They asked me if I had a "good understanding" in math and physics. To tell you the truth I couldn't answer them.
My marks are good (average is 84) but I'm petrified about going into it
I like physics and I sometimes like math.

So my question (now that you know how much of a worry wart I am)

Did you love physics and math in highschool?
Were your marks amazing?
Did you have a "deep understanding"?
And is engineering brutal in university like they make it out to be?

I AM taking all the courses I need (physics, math 30, calculus)

I am just freaking out that I'm going to get there and there's going to be all these brainy guys (I'm a girl PS) who are completly brilliant and I'm going to fail miserably.
PLEASE HELP!!!!!
