prince CEE: imagine!!!
How did he arrive @ d answer asap, Please show ur workings so that others will learn From it bro.

/peace/
am sorry. I find it difficult 2 solve, bt lookn at d questn, d ans is simply 2.

that's further maths.
A little help bro, use log to solve it

prince CEE: yeah I made a mistake, but that's not what Jamb wants to know.
r = 2tita
:.r = 30
Tan30 = x/5
x = 5Tan30
x = 5* sqr(3)/3
x = 2.89cm



Hope I got this one boss!!!
*cheers*...boss I love ur act!,....U got it right sire.
Evn attempting it alone showz ur high grade of aspiration 2wards success,God will help you

guy hlp me solve these questions nd show workings.
1)what effort will a machine of efficiency 90% apply to lift a load of 180N if its efforts arm is twice as long as its load arm?
2)calculate d workdone when a force of 20N streches a spring by 50mm.
3)a gas at a pressure of 10^5Nm^-2 expands frm 0.6m^3 to 1.2m^3 at constant temp,the workdone is?

3)a gas at a pressure of 10^5Nm^-2 expands frm 0.6m^3 to 1.2m^3 at constant temp,the workdone is?
£=90% L=180N R=2r whr R and r are d effort and load arm respectively
since velocity ratio =effort(R) distance/load dstance(r)
M.A=L/E
then £=M.A/V.R*100%
£=L/E*r/R*100%
rem,R=2r and r=r
90=180/E*r/2r*100
90*2*E=180*100
180E=18000
:.Effort=100N

2. Force=20N extension=50mm=50/1000=0.05m
workdone=?
Rem W=1/2ke^2
also W=1/2fe
W=(1/2)20*0.05
W=0.5J
