Dr.'Hesjay:am nt disputing dat fact,wot we r sayn z dat nt all skls hav their bds nd mbbs sit for mb xam in part3 different timez |
Osasu99:wich skl z dat? I tnk d xam sam 4 all part3 both dental nd medcne bt skl lik uniben z an excepttn |
I-am-Winner:i didnt mean itz harder due to d parts of body it holds but.... Dentistry in part4 or 5 in som skls borrow course frm mbbs join dem oun whereas medicine no dey do dental work datz why itzz tougher |
I-am-Winner:dentistry zz easier to enter i tnk datz y he chose it |
I-am-Winner:d guy z cool right dentistry z fuckn harder deals wif skul,jaws nt only mouth |
I-am-Winner: I-am-Winner:[/color] I-am-Winner:bloody lie,tell him sum1 sayz he has lied as concernns d housemanshp salary stuff |

hesjay@,abeg mak i noe hear say u shelve mbbs for bds ui ooo.mbbs z far better than bds frm experienced and imternational practitioner,dou they r almost sam nd controlld by sam body in ds naija.as concerns pay mbbs get more pay than bds holders cuz mbbs work time pass that of bds nd their money z calculated per hr i mean in europe,evn som states in america.bds uses very fewer hrs per wk compared to mbbs.the amount bds earn per hr z more than that of mbbs nd mbbs use much more time period so they earn more than bds bt if bds were to use sam hrs as mbbs they will earn vry much pass mbbs. |
Osasu99: Omo mbbs guys spank this exam sha see scores man don dey fear smallare u nt one of those making both man n woman arouz fear.mbbs i mean |
Dr.'Hesjay:ntn yet 4nw than to dey dance galala. |
i like dzzz testimonies more of ijn wu kws wen change of courz wil com out? |
lavosier: g=GM/R2..since G is constant lets equate.9.8r^2/m^2=4.9(h+r)^2/m^2 whr h =d altitude..since m id equal,it can cut out so we av 9.8r^2=4.9(h+3)^2 removin bra we av 9.8r^2=4.9h^2+9.8hr+4.9r^2..clllectin like terms,we av 9.8r^2-4.9r^2=4.9h^2+9.8hr..wich equals 4.9r^2=H^2+2hr..completin ƌ square we av 4.9r^2+r^2=(h+r)^2....suareroot of (5.9r^2)-r=H...our H=9145.5......not so sure shau tried fg=(GMem)/r2=mg =>r2=GMe/g=GMe/4.9 eq(1) on the earth's surface,g=GMe/Re2 =>GMe=gRe2=(9. (6.4*10^6)^2=4.01*10^14 eq.1 then gives r2=(4.01*10^14)/4.9,or r=9.05*10^6m from the earth's centre now,(9.05-6.4)*10^6=2.65*10^6m from the earth's surfac |
honey: work done by gas in an isothermal process {W=P1V1*In(V2/V1)}, from the ideal gas equation, PV=nRT, and the final volume is twice the initial volume, then W=nRT*In2 , replacing the parameters in the equation, W=3*8.314*300*0.693= 5300J approx, i hope i am correct.absolutely correct! Bt it shld be 5186.5j chck ur calculator |
topsonkay: Can i show workings for the purpose of others?yes boss to mak it complete |
topsonkay: -40gud vry correct! |
three moles of a gas expand isothermally.if the initial temperature of the gas is 300k and its final volume is twice the initial volume,calculate the work done by the gas. |
steel rails 8.0m long are laid end-to-end in winter when the temperature is -10°C a)how much space should be left between them to allow for expansion in the summer when the temperature could reach 50°c? B)if tthe rails had been butted against each other at -10°c,what stress would each have to withstand at 50°c in order to prevent buckling? (for steel,take ¤=1.2 * 10-5/k and E=21 * 10^10N/m2) |
at what temperature will the celsius and fahrenheit temperature scales record the same reading? |
at what altitude aboove the earth's surface would the acceleration due to gravity be 4.9m/s2?assume that the mean radius of the earth is 6.4*10^6m and acceleration due to gravity on the earth's surface is 9.8m/s2 |

honey: the whole pulley system can be considered as a pulley having the block W on the inclined plane, and the mass 50kg hanging vertically on the high end of the pulley.... so the following can be deduced, since the block is about to move down, the minimum forward force =mg.sin30, and also the frictional forces are [1]the tension of the rope =FT and [1] static friction =0.3mg.... now £ax=mg.sin30-0.3mg-FT (since mg=W), =0.5W-0.2W-FT=ma ....£by= FT-50g=50a ...... adding the two equations, 0.2W-50g=a(50+m), now assuming the block is yet to move, a=0 (taking g=10ms-2), then the equation becomes 0.2W=500 , dividing through by 2, W=1000N m=100Kg.a little bit tricky,u cld see dat d tension in rope was nt givn datz negligible which means Wsin30=fr force so far its moving downward lik u did above.tthen Wsin30=uN WHERE N IS Wcos30 normal resolution so simply,Wsin30=0.3*Wcos30 therefore,Wtan30=0.3 W=0.3/tan30 cn u see dat d 50kg is useless |
buzyguy: ok no wahalabe back 4 d oau questns later |
a ray of light traveling in water hits a water/glass interface at an angle of incidence 30deg.calculate the angle of refraction in the glass in degrees given that the refractive indices of water and glass are 1.33 and 1.50 respectively a)19.5 b)22.1 c)26.3 d)34.3 |
a lens of focal lenght f1=12cm is placed coaxially to the left of a second lens of focal lenght f2=18cm.both lenses are thin biconvex and are separated by 24cm.calculate the magnification of an object placed 15cm to the left of the first lens. |
topsonkay: Buzyguy bro.. Pls help us post oau postume questions for this year(Physics i mean)ok no wahala |
