4llerbuntu: or better still just take it to a competent tech who can flash it. can't take more than 15 mins

Bro!! thanks for your quick response. i really cant appreciate it enough. Your explanation has really opened my eyes to the truth regarding network branded phones. I actually got the AT & T stock firmware through sammobile after a specific search on the phone model number which is "sgh-i747".
The phone has already been upgraded to 4.3 Jelly beans . As regard the flashing you talk about, will it solve the problem or its still under maybe?
Besides, do you reside in lagos? can you help me with the flashing? I will really like someone like you to solve the problem because am really convinced that you are indeed a phone specialist. Please, if you are not in lagos, kindly recommend any competent tech you know of in lagos.Thanks bro. waiting for your response!

Please i have a problem. I recently bought this samsung galaxy s3(AT&T) from a friend. when i started using it, i notice it does not see network when am inside any building, so i thought of getting an application that would boost the signal strength. I bust into this app called arizapatch online for reviving network. i downloaded it and followed all the process for it installation. After the installation, it ask me to reboot which i did. Sadly, the phone is not just booting again. it says "could not do normal booting" and some other stuff. I tried to flash the rom (because i can boot into download mode ) with various firmware i got from sammobile using odin. But Odin keeps failing during the flashing process. I dont know what to do again and this is really frustrating me. Please, any advice, suggestion or recommendation would be highly appreciated.

@ 2, I doubt if that's true. Nitrogen (1) oxide is known to have a pleasant odour and does not react with oxygen to form NO2; it is Nitrogen (2) oxide that does so. In fact, one of the distinguishing factor between N2o and o2 is it pleasant odour as both of them support combustion by rekindling a glowing splint.

vincent561: 1.N2O has a pleasant sickly smell while oxygen is odourless. There re oda differences tho.
2.reddish brown. Pale yellow when cooled.
3.HNO3....ostwald rxn
4.frm avogadro's law, we have; 32g of O2 gives 6.02 *10^23;3g wl den giv wat? * cross multiply * we arrive @ 5 * 10^22 atoms.
5. For sulphate ion, add HCl to d unknwn compound,den add a soln of barium chloride a ppt whc is insoluble in excess of d acid is formed. For carbonate ion,add an acid to d unknwn soln. A gas whc turns lime water milky is evolved. For chloride ion;acidify d soln first with HNO3 den add AgNO3 a white ppt of Agcl is formed.

Nice one. but @ 4, the question is asking for the number of oxygen atoms not oxygen molecules.

1. Nitrogen (i) oxide and oxygen both support combustion as seen in their ability to rekindles a glowing splint. How do you distinguish between these two gases in the laboratory?
2. What is the colour of Nitrogen (iv) oxide? When cooled, what is it colour?
3. Dissolution of Nitrogen (iv) oxide in water gives?
4. What is the number of oxygen atoms found in 3g of oxygen gas?
5. How do we test for the presence of tetraoxosulphate (vi) ions, tioxocarbonate (iv) ions and chloride ions?

[quote author=Ai-bi-ke]take dis smple 1,.. If the tire of a bicycle has a diameter of 14m,what wil b d value of the total distance covered in meter if it rotates 50 times( TT=22/7)
a.4400m b.2200m c.88m d.1100m
ur workings wil b highly appreciated plz![/quote]B.
D shape of d tire of a bicycle is with no doubt dat of a circle. Therefore, its perimeter say p is 2*pi*r where r = 7m. p = 44m. Rotating 50 times implies total distance d = 50 * 44 = 2200m.

[quote author=great.david]2) 70*(10-1.5)=595 kg

Prince adebayo: 500kg/'C

good one bro bt ur detailed workings may help odas....WE ARE SHARING, WE ARE LEARNING, WE ARE GROWING.

A 50W electric heater is used
to heat a metal block of mass
5kg. If in 10 minutes a
temperature rise of 12oC is
achieved, the specific heat
capacity of the metal is...

Tea pots are often silver-
coated to prevent heat loss by
A. conduction only
B. convention only
C. convection and conduction
D. radiation only

Prince adebayo: 21/100 * 0.2dm^3 of air =0.042dm^3 which is d volume of O2 dat will be used in the solving.
The remaining volume of air
=0.2dm^3 - 0.042dm^3
=0.158dm^3.
50cm^3/1000= 0.05dm^3
2CO + O2 => 2CO2
2 : 1 : 2
0.05dm^3 : 0.042dm^3 : 0.05dm^3
0.05dm^3 : 0.025dm^3 : 0.05dm^3
excess rxt of O2 =0.042 -0.025
=0.017dm^3
normal product=0.05dm^3
Volume of residual gas=normal product + excess reactant + the remaining volume of air.

residual gas=0.017 + 0.05 + 0.158
=0.225dm^3.

Now u ar talking...

[quote author=Ai-bi-ke]crect ans is 225cm3 or 0.225dm3 at s.t.p[/quote]correct bt ur detailed work wil definately help many odas

[quote author=Ai-bi-ke]crect ans is 225cm3 or 0.225dm3 at s.t.p[/quote]correct bt ur detailed work wil definately help alot.

Prince adebayo: yes nah
so 21/100 * 0.2dm^3 of air =0.042dm^3 which is d volume of O2 dat will be used in the solving.
50cm^3/1000= 0.05dm^3
2CO + O2 => 2CO2
2 : 1 : 2
0.05dm^3 : 0.042dm^3 : 0.05dm^3
0.05dm^3 : 0.025dm^3 : 0.05dm^3
excess rxt of O2 =0.042 -0.025
=0.017dm^3
normal product=0.05dm^3
Volume of residual gas=normal product + excess reactant

residual gas=0.017 + 0.05
=0.067dm^3
Anyway give your own workings and let me see.

u tried bro but remember dat air is a mixture of gases...d volume of d oda gases in d air dat didnt partake in d reaction wil also b added to d volume of d residual gas. Hop u got d gist now?

[quote author=1000bytes/sulex]why is it negative and nt positive[/quote]Read between d lines bro. Total energy is 600j. Potential energy at 1/3 of d height is 400j and i already stated dat Total energy = P.E + K.E
do i need to show u again aw d K.E = Total energy - P.E ?
We are sharing, we are learning, we are growing.

Prince adebayo: hmm,,,0.067dm^3

hmmm...u tried bt stil wrong...consider d fact that the volume of air used contain only 21% of oxygen.

Prince adebayo: 50cm^3 of CO is mixed and sparked with 0.2dm^3 of air containing 21% of O2. If all the volumes are measured at s.t.p. Calculate the total volume of the residual gas.
50cm^3

not correct. Try 2 undastand d question and attempt it again

[quote author=1000bytes/sulex]U calculated only 4 mgh warh abt d velocity It's 4 decoration[/quote]why d rhetorical question? Lookin at d question, d potential energy at d given height of 15m is 600j, which implies d total energy at any point can not b more dan 600j since d conversation of mechanical energy is constant in gravitational field.(hop u kno this);so ur answer is obviously wrong. Now, d question says when its at 1/3 of d height which means at 10m height. Here, d object is comin down, so we hav P.E and K.E. Which implies Total energy = P.E + K.E. P.E at dat point is 4*10*10 =400j. Hence, K.E at dat point will be 600 - 400 = 200j. U can read more on conservation of mechanical energy. WE ARE SHARING, WE ARE LEARNING, WE ARE GROWING.

ChocolateBarbie: A force of 5N extends a spring of natural length 0.5m by 0.01m. What will be the length of the spring when the applied force is 20N?

@ai-bi-ke, pls read tru d question again. Y did u add d initial extention given in d first statement? D first statement only gives d necesary info to calculate d elastic constant or stifnes of d spring.

[quote author=Ai-bi-ke]u tried bro....buh try it again cos u are not yet right[/quote]solve it bro.

ChocolateBarbie: (Y)

meaning?

ChocolateBarbie: What is Cohesion?

cohesion is an intermolecular force between molecules of the same kind. E.g Hydrogen bond between water molecules,hydrogen flouride.

ChocolateBarbie: A force of 5N extends a spring of natural length 0.5m by 0.01m. What will be the length of the spring when the applied force is 20N?

from hooke's law
f = ke
=> 5 = k * 0.01
=> k = 500N/m
Given 20N, e will be
e = f/k = 20/500 = 0.04m
Therefore, the length of d spring = original length + extension
= 0.5 +0.04 = 0.54m
