Hi all I develop two types of wasps:
1)Muscidifurax raptor
2)Spalangia cameroni
And now I have a real problem with Spider Mites(Phytoseiidae).
I see them mostly after 3-5 days after the wasps...

In the picture you can see 2 table.
Table-1 is the original table that I got on my question,and table-2 is my answer.
I would like to know if I correct.
In this link the picture is more clear:...

Yes but I was not sure if this components of the waste are allows to create compost.
What you think is the easiest and cheapest way to produce compost from these components ?
Thanks for...

Hello. I work at a biologic company,and we have an organic waste that we just throw it in the trash. So this is the components of the waste:
1) bran (that was digested by the maggots) ...

* mean did it with the Y-delta transform
-
given a electrical network (in the picture)
I asked to find all the current in each resistor.
so for the start I found the RT,I got RT=3.5-ohm (I did it with the Y-Δ transform).
then I calculate...
-
Yes you are correct it was my mistake :)
-
ohh yes yes now I see it, my mistake OK I solve it now.
so yes R2=3.
so I get R:2,1=3*3/3+3=1.5-ohm,now we know is in series with R3 so we get 1.5+1.5=3.00-ohm
so Rcd=3-ohm this is the...
-
"I see that in figure 1 you have R2= 3 ohms, but in figure 2 you show R2 = 9 ohms. Which is it?"
well in both R2=9ohm and R1=3ohm.where I show R2=3 ohm?
well so if you told that I have R2...
-
Oh again is happened sorry :)
-
in the picture you can what I did till I stuck.
NO.1 is the source, and NO.2 is after I found the equivalent resistance R-5,6,7 (which is in parallel).
but now I think R2 and R1 is also...
-
Ok now I got it.
Thank you very much.
-
that OK :) .so you can tell me if the final answer is Uab=3v?
thanks so much for your help and for your time.
-
-
wow you made is clear now :) now I understand it.
so as u told beofoe V = IR = 1 amp x 3 ohms = 3 volts
so this is the final answer Uab=3v ?
-
Oh yes you correct.
But I have to ask why u took the 3-ohm resistor voltage that spans points a and b:
And not the 6 ohms resistor that also spans points a and b ?
-
yes I get 6 ohms which is in parallel with the remaining 6-ohm resistor so is equal to 6*6(12)=3ohms
and this equivalent resistance is series to the last 3 ohms resistor and I get RT=6 ohms
then...
-
well I find the equivalent resistance that can replace the 6 ohm and the 3 ohm (they are parallel) so I get:
6*3/(6+3)=2ohm.
and I get a new electrical network (in the picture).
my big problem...

-
Given electrical network (in the picture).
I asked to find the electrical potential difference between A and B. UAB
I tried and not find the answer.
I really need help.
Thanks.
-
sure I can show you.
(A+C)(A+D)(B+C)(B+D)=
[(A+C)(A+D)][(B+C)(B+D)]=
[AA+AD+CA+CD][BB+BD+CB+CD]=
[A(1+D+C)+CD][B(1+D+B)+CD]=
[A+CD][B+CD]=AB+ACD+BCD+CDCD=
AB+CD(A+B+1)=
AB+CD

given the equation (in the picture)
I asked to Proof that the left side are equal to the right side.
I know how to proof that the right side are equal to the left side,but not vice versa.

given the marginal cost is equal to: 1/2*x
and I asked to Draw the Supply graph.
in the picture you can see my tried.
Hope you can help.
thanks.
-
If a manufacturer produces a quantity of which the marginal cost equals to the product's market price then his profits are definitely maxed?
I think is correct but why is correct I not so get it....
-
When I say lump I mean pupa.
Sorry about it.

Hello.
I will start with tell you what I do so maybe is will be more easy for you to try to help :)
Ok so what I do is breed a fly maggots with a bran.(I give them the barn as a food).
After...
-
tickle lol we are OK.
Thanks for your answer.
-
I can wait :)
Is not a normal homework is more like experiment.
And I ask very straight.
Thanks
-
Well is a experiment that I nned to do for my study.
And I asked to try to Development of Spalangia Cameroni and Muscidifurax Raptor and then to see what is the effective of them on the flies.

Hi.
I looking in the internet some articles about the good way to Development of Spalangia Cameroni and Muscidifurax Raptor.
So I found 1 article about it but is not gave me all the answer that...
-
Hi. Many thanks I will check them.
I hope is what I looking for.
Again I want to thank you for your answer. :)

Hello.
I got from my teacher a homework to do some experiment about fly oviparity.
So I tried it for 4 weeks,and now how do I make the fly produce more eggs?
For example if there some food...

Hello.
I want to start a business in the field of laser engraving,but I have no experience in this sector.
So I would like to know from where to start:
What is the costs,etc.
Thanks for...

OH I mean 8-2=6 mol ammonia gas now I can multiply it in 22.4
-
well at the start I got 6 mol hydrogen gas and 2 mol nitrogen gas sp I can do 6+2=8 - 2 mol ammoniagas= 5 mol now I can multiply it in 22.5 and than I get delta v? Is correct way?
thank you.
-
-
in the picture you can see the reaction.
http://p1cture.me/images/23518895930282025474.jpg
it's known that 2 mol nitrogen reaction with 6 mol hydrogen gas to create ammonia.
what is the work...
-
not wrong, I just not know how to calculate it in my pocket calculator.
if you are trying to calculate what I wrote in those formulas you get also 8.17 g/cm^3 ?
just try to calculate as I write...
-
Well this formulas I got in my book.
But anyway I solve it :)
Thanks you :)
-
Is speak about Cu with radios 128pm
-
OK I did it but:
look on the picture I want to calculate it and I get as a result 21.2
but I know the correct answer is 8.17g/cm^-3
what you get?...
-
Yes I know in this formula I did mistake
-
"The volume (V) of the unit cell is equal to the cell-edge length (a) cubed."
http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch13/unitcell.php
-
lol forgot about this formula.
I just speak about the formula for length of the Edge :4r/sqrt3 is give us a
and for the volume for unit cell =a^3 .
you can see it in my former post up hree :)
-
OK thanks.
Last thing what do say about my way?
