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

buzyguy: D=vt=4 *10^-3 * 3 * 10^-3=12 * 10^-6m

try again by usin echo 4mula,cuz of d word reflection

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

buzyguy: Bt u typd 2secs instead ov 2.2secs

@buzyguy wic txt buk r u using,or is past questn u r usin 2 set d questns

buzyguy: Anoda:as the tension in an elastic string is increased frm 100N to 180N,the string extends by 10cm.the workdone in the string z,a.8j b.10j c.14j d.18j

Workdone in a string=average force*extension
therefore,average force=180+100/2=280/2=140N,extension=10cm=0.1m
workdone=140*0.1=14j

The wavelength of a stationary wave z 36.0cm.what z d distance btw a node n d nxt anti-node
2)A wave of frequency 10HZ forms a stationary wave pattern in a medium whr d velocity is 20cm/s.d distance btw d adjacent node z
3)radio waves emitted 4rm an antenna are pickd up by a radar afta reflection 4rm an aircraft in 4*10^-3s.how far is d aircraft 4rm d antenna(v=3*10^3m/s)

buzyguy: Distnce frm da hunter to wall wen he firez z 330m,d=vt,330 * 1.den x=412.5-330 wich z 82.5m

Initial dist 4rm clif x1=412.5,final dist=x2,echo time t=2.2s.sound speed v=330m/s
x2=vt/c,330*2.2/2=363
dist moved toward cliff,x=x1-x2=412.5-363=49.5m

buzyguy: Nt b

Ans z c

buzyguy: Anoda1:an object slidez down an inclined plane from an initial height of 30m.itz velocity at the foot of the plane z 20m/s.the percentage of itz initial potential energy wich z dissipated as heat z,a.33.3% b.50% c.60% d.none

D

a man stands one-third of d way btw two walls and clap his hands.he hears two distinct echoes 1s apart.if d speed of sound is 330m/s,d distance btw d walls is...JAMB 1980 QUE 45

a hunter 412.5m away from a clif,moves a distance x 2wrds d clif n fires a gun.he hears d echo 4rm d clif afta 2secs.calc d value of x(speed of sound in air=330m/s)

buzyguy: Anoda:a pipe organ X produces a note whose pitch z twice that of the note produced by a secnd pipe organ Y.if the speed of the wave in X z v,then the speed of the wave in Y z,a.v b.2v c.v/2 d.4v

Sori bro d ans z v/2,didnt read d questn vewi wel b4
Z dat ans correct

buzyguy: Anoda attempt:a lift of weight 30kN movez upwardz through height of 20m.if 25% of the workdone on the lift z used in overcoming friction,the work done is a.4.5 *10^5j b.6.0 *10^5j c.7.5 *10^5j d.8.0 *10^5j

ans z A

emmyeuler1: ...Broda pls help me out because i am not good in physics....phase difference =[2(pie)(x)/lamda] =(2XpieX20)/50=4/5PIE

Correct

buzyguy: 20/50=2/5landa

wrong,,,Try again

a progressive wave has a wavelength of 50cm.calculate d phase difference btw two points at a distance of 20cm apart..

shakur07: And yhu sure say d tin go cum out in jamb sha?? I mean dose two novels

D novels no fit cum out,dey jez wan sell dose books ni

emmyeuler1: I PUT IN 4 BOTH JAMB AND DIRECT ENTRY BRO.....

i tot as much cuz ur questns 4 d chem thread sounds lyk postjamb/part 1 quetns,wey jamb no dae ask...#gbam#

Doctor20002: If u see me drive by HOLL@UR BOI still me TAYO a.k.a doctor............... Is our MEGA CARNIVAL 2DAY @ OLABISI ONABANJO AGO IWOYE..... I hail all u.i aspirant nd my enemy like frd....... MBBS CANDIDATE..... Wich u success in ur upcoming jamb......JOSEBOY ND TOLULOPE SPECIAL GREETING 2 U

i hail bro,,,,aw prep?

bayern munchen vs fcb
dortmund vs real madrid

gud evenin guys!!!
@all pptites aw revision tinx

hello evribody...
shakur say 1 nau,fynest say anoda 1....shey na fb b oga at d top or shakur#gbam#

shakur07: Am nt even sure of d success of d@ cbt of a tin ...y jamb no kuku let everybody do cbt jooor..

Abi,if care z nt taken it wil affect sum cbt candidates

Atesunate15: sure anyway givin us more time to revise

letz wait til thursday...wen u wil start printin anoda 1,daz if dae dnt postpone it again...

Atesunate15: cbt Candidates suld note d@ d date for dia exams is nw May18-June12 reprint ur slip after April 18 to knw ur day of exam

bros d cbt changin tinx go don tire u...
tenk God i chose ppt

jamb with dier cbt wahala....heard dey av changd d date again.na wa o

Becalina: anoda one of us: welcome

Yeah

@becalina neva knew u applied 4 medicine,,,and ar u true wif ur syllabus n if u r on 2go,u can drop ur u.name

labodinho: i have unilag last yr n last 2 yrs past qustn maths wich am thru wif.Jxt need more mathz datz all.

Guy i fear u o,maths guru,chem guru,eng guru,phy6 n bio guru,
u b chairman...
wanna b off 4 sum days guys.goen 2 buk villa 4 revision

i wan reach buk village comebak,,,final prep
Hail @all medicos

labodinho: Anybody with online english and maths practise link?

Wetin u wan use maths do
