HAPPY SUNDAY

Hapi sunday to my snr boss in d house....let me point out sometin here anytin u are doing here is nt for odas alone but also to help urself so guys lets bring sometin up to celebrate our sunday enjoyment [color=#990000][/color]

Drop ur whatsapp phone number i will add u on group chat

Hey guys lets hook up on whatsapp add me on 08162792481 or 08166492397 But d first number is better

Halpher:
The difference btw fleming's right and left hand rule is that..?

i cant really remember it well but i believe dynamo i.e d conversion of mech to elect dats is fleming left hand but d conversion of elect to mech has to do with fleming ryt hand

Yes bro dat was a mistake

Halpher:
At the pole angle of dip is always..?
A)0 degree
B)90 degree
C)180 degree
D)45 degree

is between o and 90 degree wen d angle of dip is at d north pole it is 0degree but at d equator is 90degree

Add me on ur whatsapp 08162792481 or 08166492397

Halpher:
In an electromagnetic induction,the magnetic pole and the solenoid exihibit what type of motion
A)translational motion
B)rotational motion
C)relative motion
D)random motion.

C is correct because it exhibit two types of motion

Update resume later

Halpher:
In the formation of anti-knock agent lead iv tetraethyl(pb(C2H5)4 which of the following element is use??
A)Na
B)pb
C)C
D)none
E)a and b

lead is use because it increase d octane rating of d fuel making it a branch chain hydrocarbon
