Thankyou Ms.Sue for finding the site for the Broughton airbus pictures. They were very helpful .

Are you guys stupid? Nobody cares if you don't know. You don't need 50 differant people saying "I don't know this. I don't know that". This is basic science and you people can't understand. I suggest you get serious help. Presto! Vamos! Rapido!

Explain why H2O and NH3 are both dipole-dipole interactions yet H2O boils at a significantly higher temperature.

I think you mean third second

BUMP!

your all idiots!!! both .09505 and 3.3 are wrong were doing it in a computer program and we reworked the problem!!!

the answer you did last night was wrong. sorry DrBOb :{

3. s=m and m^3/m is m^2. the square root will be m.

Please post the answers for 1_4 and 1_5

You can say "On dit X" (One could say X) or "Le mot est X" (The word is X)

7M??

In the Alps mountain range of Europe, where the huge amounts of snowpack make for a skier's dream destination, climate change has had a negative impact on the amount of snow they receive each year. Due to warmer temperatures caused by a steady increase in temperature in the earth's atmosphere, the quantity of yearly snowfall has become less than usual, and areas receive more rainfall than snow. When snowpack melts and fills streams, it is then used for drinking water. However, climate change has caused the snow to melt earlier in the spring than normal.

your dumb. learn this yourself!!

The work is 0.00J because the sculpture's speed is constant, and if speed is constant a= 0m/s^2 which makes the F= 0N and W=0J

no, in order for the sides to be parallel, same side interior angles should be supplementary... in your diagram, (50+37) + (50+37) = 174

Damon is Stating that- F=1/T T=2*pi/w so T= 2pi/sqrt(k/m) using our values T=2pi/sqrt(682/13.50)=.884004 Therefore F=1/.884004 -->=1.13121 For the second part acceleration=Aw^2 which must equal the acc. of gravity(g) g=Aw^2 w=sqrt(k/m) so w=7.107638 plugging into our equation the equation g=Aw^2: 9.8=A*(7.107638^2) 9.8=50.518518*A 9.8/50.518518=A, so A=.193988 meters which is about 19.39 cm

Thankyou so much Damon! I just confused where to put what numbers and what Equation to use. Also to clarify: Constant Speed is always = V1 Average Speed is V2= Also how do you know when to use -9.8 m/s/s as constant acceleration and not 9.8 and also using 4.9 or -4.9 m/s/s?

Mr. Steve, could you do an example using A. for me. I am still confused as to how you actualy plug in the numbers. I am also confused on sine and cosine and tan.. Please show step by step. That'll help A lot!

Just needed a refresher. Thanks.

length of each side of rhombus: a = sqrt[(AD)^2 + (BD)^2] / 2 Solve. a = 5 cm

What are the major changes?

The question is an example of uniform circular motion -> circle. kph to mpm (meters per minute): 72kph -> 1200 m/min cm to m: 84 cm -> 0.84m circumference of the wheel = pi. diameter = 3.14 * 0.84m = 2.6376m length of 1 revolution = circumference = 2.6376m in 11 min: number of revolutions = 1200/2.6376 = 454.959m/min

x = arctan[cot(10pi/9)] = arctan[1/tan(10pi/9) = arctan[1/tan((9+1)pi/9)] = arctan{1/tan([(9/9)+(1/9)]pi)} = arctan[1/tan(pi/9)] tan(x)-1/tan(pi/9)=0 [tan(pi/2)*tan(x)-1]/tan(pi/2)=0 tan(pi/2)*tan(x)-1=0 Express in sin and cos. Use identities also. (lol, go solve the details. too lazy to do it.) --> cos[(pi/9)+x]=0 Find the arcos of both sides in radian form. (pi/9)+x = pi/2 x = (pi/2)- (pi/9) x = 7pi/18

Try solving the problems first on your own and check if the answer you got is correct. tips: Simplify the form like sec(x)to 1/cos(x). if the problem is the arctan, arcsin, and the likes, try to convert the equation into something like this: x = arctan (cot(10pi/9)) tan(x) = cot(10pi/9) then find the arctan of both sides once you simplified the right side. arctan(cot(10pi/9))= 7pi/18 sec(arccos(-1/6))= -6 csc(arcsec(5/3))= 5/4 sin(2*arccos(sqrt(5)/5))= 4/5 Good luck solving! :D

Expand first the equation. Find the intercepts. Find the domain and range of the function. The intercepts will serve as the turning points. Since the leading coefficient (of x^3) is positive, the graph of f is up on the right and down on the left and hence the range of f is the set of all real numbers. Or to make it simple, assign values of x and y and place it in a table. Plot the points in the graph and connect the dots.

Circle.

No one likes those subjects. They are all lying. (Just kidding!) English: 40*(3/8) = 15 students out of 40 likes it. Math: 40*(2/5) = 16 students out of 40 likes it. Science: 40*(3/4) = 30 students out of 40 likes it.

Speed formula: s = d/t distance (d) varies directly as speed (s): d is proportional to speed. d is also proportional to time (t).

For conformity and order.

SA = 6*a^2 = 6*(1)^2 = 6cm^2 the question just confuses you.

F = m*a a = F/m F1 = m1*(12) F2 = m2*(3.3) F1 = F2 m1*(12) = m2*(3.3) m1 = m2*(3.3/12) 1. m = m1-m2 a = F/(m1-m2) a = F/[(m2*(3.3/12)-m2] a = (m2*3.3)/[(-29/40)*m2] a = -132/29 m/s^2 (<-- goes to negative direction) *if m = m2-m1, a = 132/29 m/s^2 2. m = m1+m2 a = F/[(m2*(3.3/12)+m2] a = (m2*3.3)/[(51/4)*m2] a = 44/17 m/s^2

I don't get the part where you got the .00509 mol HCl. This is how I solved it. Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O Note: M (molarity) = moles of solute / liters of solution m (molality) = moles of solute / kg of solvent 24.81 ml --> 0.02481 L Tip: to make ur life easier, set the conversions in a table. Volume of HCl: (1L HCL / 0.1244 mol HCl)*(2 mol HCl / 1 mol Ba(OH)2)*(0.1026 mol Ba(OH)2 / 1L Ba(OH)2)*(0.02481L Ba(OH)2) = 0.0409L HCl

Use reference for starters. Watch drawing tutorials. Research. And most of all, practice.

^ lol. anonymous answer is very smart. xD

x = cost of 1kg flour y = cost of 1kg sugar 5x + 4y = $ 14.80 x = (14.80 - 4y)/5 3x/4 = 3y/5 (3/4)*[(14.80 - 4y)/5] = 3y/5 2.22 - 0.6y = 0.6y 1.2y = 2.22 y = $1.85 x = $1.48

Thanks. :D
