it flies at this angle and a wind blows directly east at 520 N, it acts with this force due east every 100 meters the bird rises, so how much work is done on the bird during each 100m of its rise by this force... having trouble setting up my free body diagram to determine correct angle and stuff... help please!!!!

Best answer to first correct response, thanks all

Monochromatic light ( wavelength= 593 nm ) is incident normally on the diffraction grating containing 600 lines/mm. Find the angles at which one would observe the first order maximum angle1 and the second order maximum angle2.
If the distance between the diffraction gratings and the screen x = 0.300 m, then find the positions of these diffraction maxima on the screen y1 and y2, respectively.

Any idea how to set this up?

everything went well
but until about 5 mins after the lady inserted the needle in to my vein, and there was about half pint up, the blood stopped flowing, and instead, the blood went back to my vein and caused it to swell up
and that lady had to take the needle out
what happened?
i'm an athlete, i'm healthy, my vein is big, though.
and she said she likes my vein :DDD

at my house. first it was just little clicking noises in my room. like someone was clicking their tongue on the roof of their mouth. then one night it was around 1am i was in bed trying to sleep, it sounded like a man was standing over me right next to my ear and very firmly said "no". i looked up(i was very shaken at that piont) no one was in my room. i laid back down and heard some one walking around in my room. i tried to figure out what i could have been, but found no answers.then a few months latter i was down stairs on the computer and i heard what sounded like people talking in the kitchen. i got up to look and know one was there. the next thing that happened was i was upstairs in my room (i was the only one awake) reading. i looked up and saw a little solid ball fly into my bookcase. i searched and didnt find any thing.
the next night i had my light off (again trying to sleep) and i heard a womans voice say "hush''................ details coming hang on.

Two substances, W and X, react to form the products Y and Z. The following data shows the # of moles of the reactants and products involved. Use the data to determine the coefficients that will balance the equation:

W + X => Y + Z

Reaction Data:
Moles of reactants -- W: 0.90, X: 0.30
Moles of products -- Y: 0.60, Z: 1.20

Am I right?

1) Is (x+2) a factor of 2x^3 + 7x^2 +5x - 2?

FOR THIS ONE I GOT: Yes
---------------------------------------------------
2) The height of a flare is described by f(x) = -16t^2 + 320t + 50 (t= seconds). How long will it take to flare to reach its highest point and what is the highest point?

FOR THIS ONE I GOT: For this one I got time is 10 and height is 150.
----------------------------------------------------
Matching: (a) f(x) = x^2 + 2
(b) f(x) = ½(x+2)^2– 2
(c) f(x) = -(x-2) + 2
(d) f(x) = 2(x+2)^2 + 2

3) only function with a maximum point

FOR THIS ONE I GOT: (c)

4) narrowest graph

FOR THIS ONE I GOT: (d)
