buzyguy: Ok,i tot u wld finish it up.30000*20 * 100/75=8.0 *10^5j

Mr buzy what u did wasnt correct...check page 192,example 7.9 in m.w anyakoha for more clarification

buzyguy: (2)0.2/10=v/f=landa=0.02cm,distnc btwn adjacent node z 1/2landa =0.02/2=0.01cm

U tried...v/f=landa,20/10=2cm
dist btw adjacent node z 1/2landa
whr landa=2,dist btw adjacent node =2/2=1cm
@Emmeur wic phy6 txt buk r u usin

I use all txt i see cuz i normally borrow,i only av new skl nd essential physics.atimes nekson nd parka,bt nt dat useful anywy cuz we r dealn wit jamb.

ok,mine z d two okeke,calculatn in phy6 by omotosho,all inclusive calculatn in phy6.i wil try n get dose buks u mentiond above...wat abt bio n chem,n wic skul do u attend presently

Oh,thks i wz tryn to convert it to m nt cm

Tenx a lot bro...cuz i want high jamb score,i dnt want 2 joke wit even d simplest questn,,,

I wil fnd and chck,bt if itz sam questn dat means da both txts r wrng

A force of 100N is used to push a body up a plane inclined at an angle 15deg. To the horizontal.if one-half of da work done by the force is used to overcom frictn,the weight of the body in newtonz is,a.50/sin15deg. B.50sin15deg. C.100/sin15deg. D.100sin15deg.

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

Perpendicular forces=6+8=14 f=ma;a=f/m;14/4=3.5

ANDREW2EIC: Attempt this:

A motorcycle of mass 100kg moves round in a circle of radius 10m with a velocity of 5m/s. Find the coefficient of friction between the road and the tyres.

N.B: show full working in all the questions.

c.frictn=F/R...R=mg..m=100kg,g=10..R=1000N...F=mv^2/r..F=100*5^2/10=250N;C.frictn=250/1000=0.25
