Thank you so much!

For free Need homework help with health

i got no idea...can you help me?

"are" is the verb

i don't have a book i have do this research on the internet and this test is very very hard

no we don't but thank you for you help though

that's not really one of the choices

1.a (static friction is pushing up on the box to keep it from sliding down the incline) 2.b (static friction is pushing down on the box to keep him from moving it up the incline) ^^friction always pushes the opposite direction of the force acting on the object^^ 3.Fphysisist > Ffriction (they must push with a greater force than friction otherwise the box would stay stationary)

x=1 subtract x from both side. divide 3x.

i was thinking step 3,5,2,1,4 but it said i was wrong

that wasn't it i'm so confused

John Grisam is the author of "The Street Lawyer."

Yes this is right.

New Year's day occurs on January the first. Numbers under 100 need to be written out.

Julie, do you still need help?

ahh it didn't show

ahh it didn't show o / \ \\ / -CH+

I do have a picture but I can't show the url well I believe its a cyclopentdiene the number is going from the right the 1 is a oxygen and the 3 is CH+ and the double bond is located between 4 and 5

like this? img198.imageshack .us/img198/7855/trialt.jpg

oh thank you but when I tried it seems there is another structure in which all atoms have their octet

ahh I got it the C5 and O need to be double bonded

w is work

I got 1518 kJ/mol using that equation, but I still got it wrong. Did I do something wrong?

0.04319 moles F3O4 Specific Heat Constant: 4.18 J/mol*C

Hi, actually Bob, your answer is not 30 degrees, but 60 degrees. 30 degrees does not refer to the angle inside the triangle formed by the x and y components.

sorry. Determine the molar mass of the unknown acid. Determine the molecular formula of this acid.

Can you explain how you work the problem? I know its a proportion but I don't get it?

Thank you sir. I appreciate it.

There are 3 portions. The next one is at 0.50 m and the last one is when the rock is at 1.0 m.

The first one should read HC2H3O2. yes the second one is phenol

3.2*10^-26

sorry, i meant smyrna and marietta.

i don't get what you're saying.. that would work for all 5 of those things?

and is the final velocity 45/7?

Is the initial velocity 0?

which end are you looking for?

260

wait let me reword my question... i am having trouble clearing up my thesis. I feel like i have the idea but it doesnt set me up to write an organised paper.

if you find the decimal value for each of these you will be able to easily tell the order. for example: the decimal value for the fraction 3/4 is .75 hope this helps!

okay thanks! because i am having a difficult time writing an essay i have! but that helps thanks

okay thanks...but don't you have to use roman numerals for elements in the "d" block?

Above answer is completely wrong.. it seems he forgot that it's an initial value problem

I got the x-component to be: 10+8.66+3.42 which is 22.08. But I also have to divide that by the total time that the ant traveled, right? So that time would be 5.3? I got 4.166 when I divided it but the correct answer it supposed to be 3.19. I really don't know how to get that answer. Could you please check my work please?

Thank for you the explanation! But I'd like to ask, how come the last equation isn't V^2/g = 15.2 + 12(2Vsin45/g)?

But is centripetal acceleration the same as average acceleration? What's the point of the problem giving information about time if it's not even used in the process?

Oh okay. I think this makes sense. Thanks for the explanation! For the first Vx, how come the 5.8 is negative?

Okay I understand the problem now and I got the answer right doing it your way. Thanks a lot for the explanation. It really helped!

Sorry. It's supposed to be wall and how many walls they can paint in 1 day.

First you have to convert the miles into meters. There are 5280 feet in a mile, then there are 12 inches in a foot, then 2.54 centimeters in an inch and then 100 centimeters in a meter. So you should get ((262.4)(5280)(12)(2.54))/(100)= 422291.8656 meters. Speed= distance/time 6.2 m/s = 422291.8656 meters/ T (s) T (s) = 422291.8656 meters/ 6.2 m/s T (s) = 6811.59123 seconds

So answer = 4540! Yes physics 221 students, this answer was brought to you by my failure to complete Mastering Physics problem and ended up pressing the show answer button

May my sacrifice be beneficial to the common good.

AB + BC = AC (2x-1)+(4x+2)=25 x=4 AB = 2(4)-1 = 7 BC = 4(4)+2 = 18

Sorry, not value.. I need an approximate length... in Angstroms.

He was buried six down and eight across

I found these web sites before but it does not tell me who it was. Please help.

Thank you Ms Sue.

I kinda wrote my equation wrong so heres a new version: y' = (0.30 cm) sin[(π/3 cm^(-1))x] cos[(55πs^(-1))t]

Thanks I got it now.

I'm having some trouble using these sites

146.13 feet

Why did you divide .06 moles by 4? Is it because there is a 8:4 ratio of C and Co?

Oh okay. Yeah I did convert wrong. Thank you.

oh sorry the diameter is 8.4mm and the question is asking for the How much energy is transferred to her eardrums each second ?

The range away from the stage doesn't matter?

Weds to Thurs

I thought I needed to do 9/10 x 7/1 which is 63/10 = 6 3/10

thank you

In 45 seconds. 9,18,27,36.45 15,30,45

They did the right work but the answer is 40 grams. That is what it says in the book.

im getting 104 hours but the correct answer is 125 hours?

bobpursley forgot to put the second mass in the equation. whenever there is a v^2/r , remember to multiply it by mass. tension[low] = mg + (v^2/r * m) tension[high] = (v^2/r * m) - mg

85 x 8 = 680

Shouldn't the answer be 1.62*10^4V? Unless i'm putting the numbers in wrong. Please help

Hm, I've never done integrals using that method before. I'll check it.

Ann, Mara, Jenny, Tina, and Sue are sisters. Two of the five sisters must help their father at his business each Saturday. How Many Combinations of two sisters are possible?

0.11 m, so the center of mass of that part of the chain is 0.055 m below edge. W = mgH = (0.021/3)kg*g*(0.055) = ____J notice that the kg is different.

1.d,2.b,3.c,4.a,5.a,6.c,7.a,8.d,9.b,10.b,11.c,12.b,13.c,14.a,15.b,16.b,17.d,18.c,19.d,20.b I did miss one but not sure which one it was.

look at 2 pounds as 6/3 pounds, (or 6 portions of 1/3 pound of beef.) Then you have an even number to compare with 6 cups. if you only need 1 cup, then you only need 1/3 pound of beef.

Nevermind i figured it out. 30.1 years to maximize value

Oh, ok well i came out with a pH of 5.22. pH = pKa + log A/HA. I came up with .15M as A and .05 as HA. So 4.74+log(3)= 5.22.

5. K =5 J since the only force acting on it is gravity, it's a conservative force. That means the energy is only transferred from U to KE and never lost. We use the formula: E= U + KE At its max displacement, KE=0 and E must equal U. It says that at its max displacement U=10J so at that point E also equals 10J. So if E=10 and U=5, KE=? E= U+KE 10=5+KE KE=5J

I recently had an essay on illegal immigrants in the United States and I wrote in there about Mexican workers in the US sending money to Mexico and I got a 100 so I believe A is right.

I don't get this too, can you help me too? Im a fifth grader too so I cant do Algebra.

Sorry for a useless reply, but Kathryn, if you wrote a novel you wouldn't be using "u" and "ur"

(a) 114.147 m (b) 778.4605 m

Yes

You can compare it to the hardest thing you'll go through up to this point. You'll go through changes, get teased because of those changes, and you'll worry too much. As you go through middle school, remember this, "I can do this. I am awesome." You'll be just fine. Good luck.

Q2 answer is 3?

the factorization of 18 is 2x3x3, and the 60 is 2x2x3x5. so the question is asking the greatest so 3 is not correct? maybe 2?

i am so confused, can you teach me?

6 is the largest common factor

It is better to use fractions when it is on top of other fractions, for example 2/3+2/4 ----------- 2/5-2/6 Because then you can get a common demoninator and cancel For decimals I don't know pretty much everything else

Did you type that in right?

Did you try distributing

over 9000

Ah Yes! Thank You
