@thinker my good friend,, nobody pays anybody for services rendered here, but people re ungrateful. The worst is dat most people want to use things posted here to generate money for themselves. They claim they can deliver, ask candidates to subscribe for both waec and jamb, thus waitin for us to post and they copy and send to their candidates. This must stop and that was why I switched of my phone since morning.
Last yr I was arrested by the police where I went to get the question papers, this is the level of sacrifice I ve paid.
By Gods grace from Monday lets see wat happens, all waec questions re free bt answers may be on special arrangement

Na xo ma guy. Sum pple r up to no good at all. Imagine such nonsense and cheat. Copyin n paste to extract money from odas

Gud a.m Mali n others,i nid Physics obj and theory

I do things I do here with d sold aim of assistin u. I post this things in two sites bt this is my favourite. But to my greatest suprise, some persons i 2go and do whatsap with wil beg me they want jamb and stil go behind to promise people they can deliver and extort money from them. Well, by God's grace I ve neva failed u in my promises bt if I afterwards fail u by nt givin u this answers wt wil u tell ur candidates?

Mali nd others plz I need physics obj nd theory

12a) The boiling point is
the temperature at
which the vapor pressure of a
liquid equals
the external pressure
surrounding the liquid.
Therefore, the boiling point of a
liquid
depends on atmospheric
pressure. The
boiling point becomes lower as
the external
pressure is reduced.

(6a) A
harmonic is a signal or
wave
whose frequency is an integral
(whole- number) multiple of the
frequency of some reference
signal or wave.
The term can also refer to the
ratio of the
frequency
of such a signal or wave to the
frequency of
the refer
Triangular law which states that
if a body is
acted upon by two vectors
represented by two sides of a
triangle taken in order, the
resultant vector is represented
by the third
side of the triangle

(3)current=1A,
mass=0.66g, t=30x60=1800secs.
Formula=M=Z*I*t where
m=mass,
Z=electro chemical equivalent,
I=current,
T=time, I=0.66=0.00033xIx1800,
I=0.66/0.0033x1800 I=0.11A.
