valence shell electron pair repulsion theory,organic chem topics include hybridization,stereochemistry,optical isomerism,nucleophiles and electrophiles,

Thanks @emmyeuler,anybody with d 1 4 physics or any addition??

Salute to everyone, plz how can i convert voltmeter to ammeter and vice versa

tbro u failed it,its by connectin a low resistant shunt in parallel

guy...d oda guy iz corect just dat he ansad da bakward reaction and u ansad da 4ward reaction...lolz

DONT 4GET THE FACT THAT THE QUESTION SAYS VISE VERSA

ANDREW2EIC: Attempt this: A body of mass 4kg resting on a smooth horizontal plane is simultaneously acted upon by two perpendicular forces 6N and 8N. Calculate the acceleration of the motion

is 2.5

Sori bro,didnt c d vise versa .....we r ryt

Calculate the magnitude of the electric field intensity between two plates, 15cm apart, if the P.D between the plates is 4.2V.

johnpaul1101: Calculate the magnitude of the electric field intensity between two plates, 15cm apart, if the P.D between the plates is 4.2V.

E=V/d=4.2/(15/100)=28N/C

emmyeuler1: E=V/d=4.2/(15/100)=28N/C

thanks emmy

more qst nw u guyz.....dis thread is so dull!!!

pls i wnt som1 2 xplain hybridization 4 me i'm contemplating on 1 area dia

Which of d following trioxocarbonate (iv) compounds will not decompose
a)CuCO3
b)K2CO3
c)ZnCO3
d)FECO3

B)K2CO3....Mostly group one element of trioxocarbonate react with water to product H2CO3 and further by heat we get CO2 and H2O.....Am i right?

Group 1 element of trioxocarbonate do not decompose on heating. That is why k2CO3 answer's the question.

hn hmn u run commot 4 our nairaland. *winks*

increase in pressure of water a. incrns d meltin pt b. lowrs d meltin pt c. has no effect on d meltin pt d. has no effect on d boilin pt

ice or wata? If its for ice...it decreases its meltin point(regelation)...iif its 4 wata ..it increases its bp

Gudevening every1, plz i would appreciate your help here:
the diagram associated with this shows a 6V battery of internal resistance 0.5ohm, connected to three resistors of values 3ohm, 4ohm, and 5ohm as show. Calculate the current in each resistor, the p.d across the 3ohm resistor, and across the parallel resistor
(question 13, exercise 4, book 3, page 397 of new school physics for senior secondary schools by anyakoha)

@JOHNPAUL,FOR PARALLEL RESISTORS 4 ohms and 5ohms,1/R=1/4+1/5 Hence,R=5.22 ohms....E=I(R+r)....6=I(5.22+0.5) I=1.05A p.d across 3ohms resistor=1.05(3)=3.15V.....Therefore,p.d across parallel resistors4ohm and 5ohm=6v-3.15v=2.85v....

why should i be banned 4 posting the solution to the physics question above....it's not fair!
