buzyguy: WELL,lemi tel u sumtyn 2day nt evrybdy u seek admssn wif or u fall in sam life issue r supozd to be ur mind..

buzyguy: Hmm,thk God u brng out wotz in ur mind.

buzyguy: Which of the following can be adopted to prevent rustinga)eletrolytic,cathodic protectn by making zinc the cathode and iron the anode (b)electrolytic cathodic protection with the anode zinc and cathode iron (c)electrochemical,with the anode iron and cathode zinc (d)electrochemical,with the anode iron and cathode tin?

Fynestboi: Nbdy is ready to ansa ur questn coz dis place is nt meant 4 dat.. Undastood... Am sure deir 2 diff thread 4 science student...pack urself deir and dnt disturb d major aim of dis thread. Peace.

Atesunate15: i pray that by this tym nxt year wen we will be celebrating anoda new monthe whc is march. we will be already in UI, do i hear u say Amen

ikeola6: fscos¤2*3*cos60(0.5)=3joules.

Jasboi: f=uR, u= co eficient of friction, R=normal reaction i.e the weight. Our u=5 v= 0,s=10 so u^2=v^2+2as givs ,25=0+2*a*10 a=0.8ms recall F=uR f=100*0.8=80. 80=u*1000 u=0.08

larri: since d force is perpendicular d force will b 10N according 2 vector diagram of d side of triangle using pytagorus thorem.. F=MA
10=4A
A=10/4
A=2.5m/s-2

Atesunate15: ML²T³I^-1

Tizzie: F=MA F=8+6=14 =14=4*A
A=14/4
A=3.5m/s-2

Physics:
when a positively charged body is brought near a neutral gold leaf electroscope,what happens to the leaf?

larri: 8N-6N=2N
mass=4KG
F=MA
A=F/M
A=2/4
A=0.5m/s-2

joseboy199: Continuation..
250N is aw Fc..therefore coef=F/R,,,whr f is 250N,and r is 100*10=1000N,
coef=250N/1000N
Ans=0.25

Tizzie: MV2/R
M=100,V=5,R=10
100*5*5/10=250rads (not sure)

Atesunate15: since the guy sed its wrong buh
since (x²-2)(x²+4)= x⁴+2x-8-------------(i)
and we are looking for x4-8 so we will just subtract 2x from equation (i) it will nw bcom
[x⁴+2x-8]-2x
x⁴+2x-8-2x
2x will cancel demselves nw x⁴+2x-8
so x⁴-8 will be (x²-2)(x²+4)-2x

Becalina: I'm in love with two universities and I don't know which one to choose and they are University of ibadan and University of Ibadan. There are two universities in Nigeria and they are :- university of ibadan and the rest

Atesunate15: no it is nt oxidation number, to help u a litu bit coordination number (C.N) is the number of ligand donor atoms(hp u knw watr is called ligand) directly bounded to the central atom

Atesunate15: (x²-2)(x²+4) -2x²

Atesunate15: (x²-2)(x²+4) -2x²

Atesunate15: wat is the coordination number in the following complexes
(a) Cu(NH₃)₄⁺²
(b) Al(OH)₄^-1
(c) Co(SCN)₄^-2

t.boy007:
(physics):
when an ebonite is rubbed with fur,what will be the charge of the two substances respectively?

joseboy199: the substance often use for vulcanization of rubber is....a)chlorine b)hydrogen peroxide c)sulphur d)tetraoxosulphate(vi)acid
