it did not help at all. Thanks though.
x/3 = x + 10/6
x/3 - x = 10/6
x(1/3 - 1) = 10/6
x = (10/6)/(1/3-1)
bobpursley, it's a matter of parenthesis.
The question is incomplete.
38.9 + 5.58 + 7 + 15.8
Significant digits will round to the whole number due to the 7.
Haha, I just noticed she asked you to do your own question.

Q: How big is Stonehenge?
Q: Are some stones on top of other stone? And how were they stacked?
Q: How did the stones get there?
Q: Did people ever live there?
Q: Are the stones heavy?
Q: Where is stonehenge?
Opps... spelled Chemistry wrong.
thanks !
Thank's for pointing that out Writeacher. I approve that Ms Sue's classic story is more in the spirit of Christmas, but I'm more in search of a story with a suprising ending. When you read the end, you're like : wow, who would have thought that...
Who would have thought...eheh last week I had a literature exam about ''The Necklace''. Thanks for the good, tragic, idea.
By curiosity, why would the father kill himself?
If other people have more ideas, be free to post. Thanks all.
Alright thank's!

Reiny is right.
I know its been a while, but I'm just wondering how drwls solved the question without resolving friction into its x-component because isn't the centripetal acceleration directed horizontally instead of parallel to the incline and wouldn't the friction force be parallel to the incline. Can someone please explain this to me.
Hey "drwls" can you explain to me how you solved a previous physics question that you answered? It's for the following question below, and it's already posted on here. Unfortunately, it didn't allow me to post the link to it, so you may have to search for it. If you do find it, I have already posted what I'm exactly unsure of on that specific page. Thanks.
Here is the question:
A banked circular highway curve is designed for traffic moving at 55 km/h. The radius of the curve is 220 m. Traffic is moving along the highway at 38 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)
Also how did you just substitute mg in for the Normal Force. Cause when I solved for the normal force from the vertical components I got:
FNcos A + mu*FNsin A = mg
FN = mg / (cos A + mu*sin A)
And I basically just substituted that into:
FNsin A - mu*FNcos A = m*v^2/R
I solved this and got the same answer as you. So I'm just wondering how did you just substitute mg for FN? Are there some cancellations that I'm unaware of?
So does that mean you can just use friction force without resolving it into its components, and so what you use in you equation would be:
M V^2/R = M g sin A - M g cosA*mu
(This is what you did in the previous example)
So did you basically just ignore the vertical component of friction because it is extremely tiny and assume that FN = mg?
I see now that my question was already answered.
I think the community will encountor many problems due to substance abuse
I don't understand why you've used 4 pi in your answer, i assume your rearranged the uncertainty principle equation for delta Px, but isnt the reduced plancks constant h/ 2pi instead of 4pi ?
Please tell me how to solve it
Thank you

For anyone finding this in the future, Ryan has the correct answer.
Emma, what was it? I need help!
A force of 9.0N is applied to a body at rest on a smooth horizontal surface.
If the body has a mass of 18.0kg and it moves in the direction of the force, find the work done in.
a. The first four second. b. The fourth second ? Pls I need answers to this question pls
Scott pls check my question.. I need an urgent answer
#bobpursely thank you very much for the reply
#scott .. Thanks for your reply
#bobpursley pls more enlightenment on the (b) aspect
#scott . you can also help me that thaty
Please how do I do that.. I am confused
How should I subtract it...
Please somebody should work it out for me
Damon .. Pls view my question.. I need your opinion
d= 1/2 at^2=1/2 (9/18)3^2 =2.25
Work =9*3
=27J ?
Am I correct
9.0*2.25
= 20.25J ..
Am I right?
It should be x^2-6x+9=0
I mean using completing the square method to get the answer
Sorry I dnt know the answer for that
Thank you Damon.
ok thx Ms. Sue i will type the question. im new to twitch so i dont know the rules.
2x^2 + 8 - 4x + 3x - 6x^2 + 7
(b)(i) Gas particles are composed of Fermions, which have non-integer spin states and must obey pauli-exclusion principles. This, these particles cannot occupy the same set of quantum numbers. This reduces the probability that these particles would exist in identical quantum states.
Bosons have integer spin states, and do not obey pauli-exclusion principles. In other words, they can occupy the same set of quantum numbers. Bosons therefore, are much more likely to be found in the same quantum state than are fermions
my answer is b

End product can inhibit an enzyme in a pathway so pathway is ‘switched off ’/cannot take place
so concentration of end product decreases
as it is used up by the cell
as concentration decreases, inhibition of enzyme decreases enzyme becomes active and pathway active again
