I Ned Help Answer I Beg Of You

I beg you i need help?

a) the forces on the disk are its weight down and tension up

the tension creates a torque on the string given by

torque = T R = I alpha where I is the moment of inertia and alpha is the angular acceleration

for a disk, I = 1/2 MR^2 and alpha = a/R where a is the linear acceleration, therefore we have

T R = 1/2 MR^2(a/R) => T = 1/2 Ma

newtons' second law tells us:
T - M g = - M a

1/2 Ma - Mg = - Ma

g = 3/2 a or a = 2/3 g

substituting into T = 1/2 Ma = 1/2 x M(2/3)g = 1/3 Mg

b) done above

c) use vf^2 = v0^2 + 2 a h where v0=0 and a = 2/3 g

vf^2 = 2 x (2/3 g)h => vf = Sqrt[4/3 g h]

d) at the start, all the energy is in PE = m g h

after falling a distance h, this amount of PE is converted to KE

remember there is both rotational and translational KE, so:

M g h = 1/2 M v^2 + 1/2 I w^2

I = 1/2 MR^2 and w = v/R

so M g h = 1/2 Mv^2 + 1/2 (1/2 MR^2)(v/r)^2 = 3/4 M v^2

solve for v: v = Sqart[4/3 gh]

You've high terms, but I'll see what I can do for you. What I might suggest is that you wait at least until you're eighteen, but if you can't wait, move to Canada. I have a couple links for you on the city/cities of Dauphin, Steinbach (which I suggest you move to), and Winkle (another place I suggest you move to). Winkler has a really good economy where they have several jobs, and have a recreational vehicle manufacturer, and to add to that, Winkler becomes home to 10-20 businessess, on average. Steinbach, too, has an economy based on farming, but greatly reduced, as the same as Dauphin. Sorry, I was too lazy to name Dauphin. On this website, you can search for apartements to stay in, name your price, bedroom #, Bathroom #, etc.! I'm happy to have found that for you, like I said, follow the links on "what's your source?" and you should find something!
-Hope it helped!

-Good Luck, pal

In dire need of help? please. I beg of you?

i'm not quite sure what your problem wants, but since it has something to do with paper chromatography, i'm assuming that what it wants is that if you do a test on the unknown mixture, we can see that since each color can be seen as different "compounds", they will travel up the paper at different rates, thus separating out. The compounds' affinity to water will affect the rate at which they travel up the paper also. A polar molecule will travel further than a non-polar molecule

I need help with a dictomous key plz i beg anyone :)?

When writing keys, I usually start with a spreadsheet, listing the organisms on one edge and the characteristics on the other. Then, try to divide the organisms in half on the basis of one of the characters. This would be your first dicotomy. Keep dividing the organisms until you get to single ones. You're lucky in that you can make up the characteristics; I have to stick with the ones that evolved in real animals. Don't take the word "half" literally; you may want to start by separating the plants from the animals.

Need math help. Please, I beg you?

Hello Katie, too many questions!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...
Calculate the perimeter of an equilateral triangle with a side measure of 8.
Answer 24 since P =3a
Question 5
Find the area of a square with a side length of 8.
Answer 64. Since A = a^2
Question 6
Find the perimeter of a square with a side length of 8. Answer is 32. Since P = 4a
Question 7
Find the perimeter of a rectangle with base 10 and height 4. Answer is 28. Since P = 2(b+h)
Question 8
Find the area of a parallelogram with base 9 and height 12. Answer is 108. Since A = b * h
Question 9
Find the area of a rhombus with diagonals that measure 8 and 10. Answer is 40 since A = d1*d2/2
Question 10
Find the area of a trapezoid with height 13, base 1 = 12, and base 2 = 14. Answer
Question 11
Find the circumference of a circle with radius of 9. Answer is 18 pi Since P = 2 pi R = 56.52

THE REST would be answered by some one else. Please don't ask too much and better try to do your home work dear. You can learn definitely. All the best

I need boobs! Help, please, I beg!?

1. Choose tops that enhance your breasts.
* T-shirts: Get tees with high, asymmetrical necklines. If you have slender arms, sleeveless t-shirts will draw your attention to them and give the illusion of a larger bust. Stay away from deep v-necks or very low scoop-necks, although vees are better than scoops. Tighter fitting tops are better too.
* Blouses: A fitted blouse with a narrow v-neck will accentuate your bust. Ruffles, lace, breast pockets, and wide lapels will also give the illusion of having larger breasts. Stay away from blouses that are too big or flowing.
2. Cross Your Bra Straps. In the back of your bra (behind, where it clasps) unhook the two straps and switch the little loophole they're fastened in. This will pull up your breasts, and make them look larger!
3. Get a push-up or padded bra. Push-up bras push your cleavage together to enhance your breasts, and padded bras add heft to your breasts. Some bras have both these features. Gel bras, air bras, and water bras work in the same way, but they may move better with your breasts to appear more natural, and you may find them more comfortable.
4. Eat more, but exercise. During a growth spurt, even if you do get physical activity, extra fat will go into your breasts.

PLEASE HELP ME! PLEASE I BEG OF YOU PLEASE!?

This book tells the story of a largely unknown piece of World War II history – the role of Navajo Indians in creating a secret code to keep military secrets out of the hands of the Japanese. The story begins with Ned Begay, a Navajo boy, going off to boarding school to learn English. In school, the Navajo children are treated badly by the white administrators and teachers, who insult them because of their heritage and try to get the children to forget the Navajo language and culture. However, when World War II breaks out, the Marines begin actively recruiting men who can speak both English and Navajo. Ned, who has to pretend he is older than he is in order to enlist, joins the Marines and becomes one of the secret code talkers, who use the Navajo language to create messages that the Japanese will not be able to understand if they intercept. Ned is soon shipped off to the Pacific and gives detailed accounts of the various battles there. Code Talker is a piece of fiction that reads almost like a memoir. This book is a great tool for learning history, for both children and adults, giving accounts that are not usually covered in introductory textbooks. Instead of focusing on what was going on in Europe during World War II, here we get to see what was happening in the Pacific side of the war and we learn about the covert code operation, which was not publicly released until a couple of decades after the war was finished. The book also covers other deep topics such as prejudice and stereotyping, providing fodder for interesting discussions. This book is dense to read though, and I would recommend taking your time with this one, letting the information sink in before barreling on to the next chapter.

This should do you fine for the introductory. Next time 'DO YOUR HOMEWORK'


For the thesis, maybe u can talk about unsung heroes nad the value of soldiers as individuals in the time of war. Just make up stuff, the good thing is that there is no right or wrong so just write something u can connect with \.

NO PRESSURE!!
