akanji2013: Calculate the energy stored in an inductor of 2H carrying a current of 5A.

emmyeuler1: since the conductor is parallel to the field, @=0 F=BILsin@=5*0.2*3sin0=0 newton

emmyeuler1: que1:if the circumference of circle equal 1 revolution and pie=3,then 1revolution=2#r=3m...for 100revolutions,distance travld by wheel=3 x 100=300m

BRAINEE123: Gbam! U can share ur questions if u have any.

emmyeuler1: @brainee...to get the points common to the equations implies solving the two equations 2x-y=4 and x+y=2 simultaneously which gives x=2,y=0....distance between Q and points common to the two lines=sqrt[(Y2-Y1)^2 + (X2-X1)^2] =Sqrt(13) units

Sadeluhv: I think dia is thread for dis,u guys shld just make use of dat pls.

BRAINEE123: For Eco student:
1.Find the distance between the point Q(4,3) and the point common to the lines 2x-y=4 and x+y=2
2. The angle of elevation of a building from a measuring instrument placed on the ground is 30 degree. If the building is 40m high,how far is the instrument from the foot of the building?

Aliciakeys: C as UI don make ppl 2 dey do private discussion.. R we nt included??

laryom1: lol.. Dos it takes a minute?

Aliciakeys: Ma papa Prof Sir Isaac Adewole wey be d vc no even wan tae me anytin abt UI. Haba!!! UI don strict even to me.. hehe

Da kingpin: UI abeg how long r we gonna wait

Isaolamide: ..use ds formula 2 solv it...f=blvsintita

Johntosyne: Chai!! Doze 1980s-1990s aspect for series technical die, i guess datz d aspect ui do lyk to ask most

dyshow: . Any way i wil try to post 1 each of maths,physics nd chemistry only Cos i dnt wnt any negative comments frm anybody here,we ar all planning 2 succeed in our ui putme by God grace, actually d past question is frm a reliable source,its ui real past question upto 2011 to b precised.
1.a wire carrying current of 10A and 2.5m in length is a field of flux density 0.14T.what is the force of the wire if it is placed 60degree to d field?a.3.03N b.20.5N c.15.3N. d.10.5N
2.which of d following will diffuse at a slowest rate?a.ammonium b.sulphur4oxide c.carbon2oxide d. Nitrogen.
3.differenciate with respect to x to the function if y=1/2x^2+2x-e^x.
A.2xplus or minus 2-e^2. B.x+2+e^x d.x+2+-e^x.
Mind u,d past question contained all d calculations nd anwers 4 each question. Nd its abt 70pages,tnk u all.

Mesopotamia: I swear,my patience is running out........why dem go dey put person for unnecessary suspense?

Johntosyne: hanhan! Y diz foul language....... Hez jst jokin nd moreover diz is a social network, u dnt av to attack any1 wif ur foul language! *no offence* jst a point of correction

Atesunate15: Doing serious jacking now 'cos I know the strike will soon be over and sonnest, know the pume day. All thanks to baba God.
I pray xo o,my broda
I dey greet all of una oo
