Latnok95: HEE - ESS - CEE - AAY - PEE - HEE Velocity my brother.. Escape velocity..


Morning nation..

okay thank you. . .without considering upthrust. . .thank u very much. I hail u

exPLIcit7: Miscellanous don't unfollow d thread...I saw his post...I just ignore it.

hehehe bro, i shud o. . .i knw it would degenerate soon

[quote author=Sir-Tunechi]Xori 4 bringin up diz 1kg issue but sum pple must have sense......in physicz mass iz directly proportional 2 weight xo equal masses has equal weight....secondly uptrust in air although itz a fluid iz too low to b recognisd in physics irrespective of the volume of solid..datz y wen doin calculationz on upthrust in physics dy wuld give u weight in air nd weight in fluid bcuz weight in air is taking as d standard weight nd nt considered as fluid(although we all knw itz a fluid)...xo weda air or vacuum 1kg of sand nd 1kg of iron re equaly heavy.... *datzall*[/quote]tunechi i av told evry1 times without number to drop that isshh so they wont block dis thread but u refused. . . . .we stopped arguing doesnt makes u or anyother right or mayb u think u knw physics more.
1. U said upthrust isnt considered in air ? Ah jst dey laff. . how do aeroplanes fly ? What makes rocket to be propelled ?
2. U said they will always consider both water and air during upthrust ? So aeroplane go enta water first shey ?
3. He even went as far by saying, w=g-u cant/doesnt exist in physics. . .ah jst dey laff. . .and e call himself engr student. . i was expecting to hear dat 4rm doc_miss but not 4rm an engr student. . .well i will show it u so dat u dont disgrace urself outside.

I told u science students dont read, read and read we read, think, think and if possible we think the picture of the experiment without carrying it out physical (that is why albert einstein is d most brilliant scientist)..And for the purpose of clarification, we are not disputing the fact that with just calculations 1kg of iron and 1kg of sand wouldnt be equally heavy. . . . U guys are saying both will av 9.82N(10N approx.) each. .but dats because u've only considered the downward force on the two objects due to gravity. Assuming that we're measuring the weight of objects somewhere on earth, we must also consider the effects of the earth's atmosphere, the upward force to be precise. Since air is a fluid, we must consider the effects of upthrust on these two objects:

Upthrust(u) = weight_of_displaced_fluid

i also noticed that u guys jst focused on w=mg because u only calculate and no experiment or thinking. But,

Weight, w = downforce_due_to_gravity - upthrust_from_fluid

therefore, w= mg -u but m=1. so, w=g-u. . .there are more complex ways to prove it but i think dat will only make u confuse d more. And we all knw dat upthrust in 1kg of iron and 1kg of sand differs but ''g'' in both remains the same so, how can they be equally heavy ? Dere will be a slight difference in heaviness, . . .i think 0.89 - 1.1.

Tunechi only resort to insult cos dats wat he can do best. . .i argue without insults cos we avnt seen each other b4 and we dont knw each other's temperaments . . .i knw u'll still disprove wat i said above cos there is somekind of a spell in ''w=mg'' and i guess dats because its not easy to change mentality & even if every1 says u guys are right, dat doesnt makes u right.

And to prove who reasons lyk an art student lyk u claimed, ask any of them and u would see whose reply they'll give. And for the record, dont think u knw more cos we are all learning. . . .am expecting ur insults cos dats ur duty.

Lest i forget, for d bolded text above, weight in air is taken as the standard weight we all knw dat but not during comparism cos shape of objects(iron and sand) is significant. . That is why a house and an aeroplane can have same mass but an aeroplane cos of its shape and concept of upthrust can fly!!!

Throwing away the concept of ''upthrust'' on planet earth is lyk saying there is nothing lyk ''matter.''

Enough said, i unfollow dis thread but i will come back wen dis dies down cos i sense dis will degenerate to something else. . .u neva can tell. Its not a foolish decision but a very wise one. . .if we happen to see in uniben, we can continue d arguement.

Swagalord18: MISCELLANOUS
you are/were right ....the sand will experience more upthrust, and thus be slightly lighter since 1kg of sand haz more volume dan 1kg of iron as sand iz less dense dan iron ...
DOC_MISS
....archimedes' principle applies 2 fluids
(fluids are liquids and GASSES)
AIR (mixture of GASSES) iz a fluid ...so archimedes principle applies 2 air also....datz y an aeroplane can fly

oga pls now abeg lets try to leave the arguement, i dont want them to block dis thread. . . .abeg na. . My oga. . .abeg

Ken excel: ...



Hmmmm.....i comment my reserve..bt dis tin na word oo..abeg make una no use fight end dis tin ooo..i hear say doctors don go on strike and dis one self pass indefinite strike..so if person break leg no hospital ooo...

Na xo una go dy argue uniben go release result on kofa una go stil dy argue, clearance go start una go stil dy argue, classes go start una go stil dy argue..go even reach matric..E.T.T .....

Abeg u guys shuld nt be infernal dats hw my mouth is o....didnt talk to anybody though..

unfortunately nor be word for me. . . hehehehe. . . .my man u funny o

[quote author=Calculusf(x)]...i dey low key ooo my oga[/quote]iwo arabinrin yii . .

exPLIcit7: weight is a measure of the heaviness of an object.

my oga, let the matter die abeg. . . . .

[quote author=Doc_Miss]Okay....weight of Fluid displaced. No arguments.

Now Look at Miscellaneous' Post I quoted....he clearly stated that If u take 1KG of Sand and 1KG of Iron and weigh it(something like that) ,the UPTHRUST would be different.

He Never mentioned anything about A LIQUID. How's that Possible Do they determine upthrust In Air now ?

Why do u derive pleasure in contradicting urself?? Is it an Hobby or something Read my post wella before quoting.. Tenk[/quote]plss oo let the matter die o. . . . Oga tunechi ur names wen u call me don reach oo. . .i beg u. . .if u still want to argue email me or let d mata die . . . . Abeg

Calculusf(x) i see u o. . . . . My main baddo. . .the only oga

[quote author=Doc_Miss]Now this is where I got Lost bro !
Cos Last Time I checked . Upthrust was the Force exerted on an Object when Partially / wholly Immersed in a LIQUID .

Or maybe Physics Advanced and Left me behind... Upthrust In air You gotta be kidding me


[color=crimson]U ain't simplifying nothing bro !
Enough of ur sophistries sire. You know....how u managed to arrive at another theory =>''UPTHRUST'' (which isn't even germane to what we're arguing on) Is really AMAZING ! More Diesel to ur elbow.
You're savvy...really savvy.
But that doesn't make u right [/color]




I wouldn't wanna drag this any further(to avoid stories that touch) cos it's obvious everyone thinks they're right...
So it's okay[/quote]1st bolded. You dont even know dat upthrust is an upward force ? Na wa o. . . .upthrust is an upward force exerted by an object when placed blah blah. . . But wat was wrong wen i said upthrust is an upward force ? Chai. . . .u don kill me for physics!


2nd and 3rd bolded- if air is a fluid upthrust takes place there ooo abi air not fluid ? Na wa o. . . . .fluild can be liquid or gas. . Air is a mixture of gases na. . Abi dem oxygen na solid ? Na wa o. . . .doc_miss don dey bury me o. . . .haaaa upthrust exists in fluids o. . .abeg. . If upthrust exist then, u will knw d upthrust on both 1kg of sand and 1kg iron is different wen suspended at d same point on the earth. . . .den how can d weight be same ? Until u dispute d theory of upthrust u wont convince me. . . .because oyibo man talk am black man must take am. . .ok i'll take it.

seriously, i think i shud stop dis arguement here. . .the more u guys kip twisting the whole isshh d more d ansa stares at ur face. . . .we arent in a vacuum we exist in a planet where there is air resistance and archimedes rule/upthrust must apply. The question we've bin arguing is a smart one but is somehow ''foolish'' cos scientists will laff at d question. Take, 8/4 and divide thru by 3 and u say ur ansa is ''2'' nd d examiner said ''2'' d correct ansa. . do u knw its valid but wit a wrong process ? But dat stuff is actually wrong. . . Divide thru by 4 and u will av ''2'' as d right ansa. abeg make una biko make we stop here. It takes a scientist to see afar . . .explicit7 i see u graduating wit 1st class in medicine continue ur vision and kip studying. . . Science is abt thinking and not reading. . . . .so stop quoting dem anyakoha, nelkon and parker, abbot etc. . .it doesnt mata ur qualification in lyf once u are ignorant of sometin, u are. Dont get me wrong , i am not disproving w=mg but the theory of archimedes says otherwise some even say archimedes nor concern d mata. . I jst dey laff. . .go check archimedes calculation if u nor go jamm where dem talk abt a body being suspended in air . . .maybe me and explicit are both wrong sha. . .abi ? Or mayb is a theory dat hasnt bin proven yet!

All of dem dat opposed dis idea couldnt justify their post and they resorted to name calling, view sirtunechi, swagalord post etc. . . I am not d type dat will lash d insult back i laff over dem. . . i shud go back and read my ss1 books ? I jst laff cos we're talkin abt physics and its practical. . .arguement is not to show us u are way better dan us, it is prove ur point and make us see reason but u guys jst resort to names blah blah. .

This thread is for uniben 2013/2014 admission session. But if u still wan argue jst try email me but if u quote me for here i nor go reply u. . . . U go quote tire. . .to those wey nor talk for d mata ever since i respect una.

All d great scientist in here, i respect una too.

Explicit7 i revere u. . . . .i would love to see u in uniben. Thanks once again.

Abeg oooo. . . .make dem nor close dis thread. . . .lets go to a science site. . . .naaaa. . . I dey beg oooo

Please if u knw u want to still argue abt many stuffs pls indicate. . . .lets meet at a site . . .make we craze our craze there so dat we nor go disturb dis thread. . . Hehehe. . .

exPLIcit7: They are trying to justify themselves by removing the word HEAVIER.

kudos to u

Swagalord18: tino waz ryt .....don't drag him in2 ur folly

is that so ?

Swagalord18: i don taya 2 argue/type oo
...*irritated*

hahahaha

Swagalord18: i kno ur typ ...
U knw u made a mistake, ...but wont accept d fact ....
To save face

hahahaha. . .i studied d question b4 answering o. . . .i'm still taking my stand.

But i'm really surprised dat me, explicit7 and eng tino are the only ones dat see it dis way. . . . Me jst dey laff una. . . Hahahaha

Winzor78: laff iyaf barber my hair

he's right

Swagalord18: lmao.... Dis iz hillarious ....
Wat r u? ....dumb?
I bin no 1 put mouth 4 dis argument but. ..this! .....rili?
....1kg of sand, ...and 1kg of iron, ...weigh the same ..i.e..non iz heavier ...provided 'g' iz the same ...i.e ...provided they r in areas with d same gravitational pull ....letz take "g" as 10
1kg x 10m/s^2 = 10N ....for both, ..nd datz their weight ....10 Newton each (the same)
Chai ...pple can twist fiziks sha

hahahahaha. . . . During ur year 3 in engineering u go get sense. . .hahahahaha . . . .

sylvalord: lol.. Very wrong.. Despite d long post.. *not contributing to the weight ish*

she is convinced but doesnt want to accept. . . . .i knw dats how it will surely end.

exPLIcit7: I have droped dz arguement...I don't wanna continue...you're pushing me and I will Ignore You...

u get sense die

[quote author=Sir-Tunechi]all of u claimin 2 knw buk shuld shut up nd learn hw can wen 2 substance already measured 2 have equal mass wuld have one heavier dan one Mass=density *volume. Iron z more denser but sand occupiez more volume either waz deir product gave 1kg xo dy re equally heavy[/quote]smh. . .not even my friend is saying d right thing. Sir-tunechi open ur eye naaaaa

view my recent post in my profile to see the current explanation oooo. . .abeg i dey wait for u for 2go. . Shuo

[quote author=Doc_Miss]Very Busy ATM . I'll Be back . LOL.
PS: u're wrong Tho'[/quote]i can see u are not ready to learn. . .u prefer to pack pipo money. .

Why is it dat wen u dont av an opposite view u wont concur ? ''u are wrong'' dats wat all of u kip sayin. . . .come out and dispute the fact. . 1kg of iron is heavier than 1kg of sand! How on earth will u say they are same ? U are doc_miss and i guess u are a doctor but na doctor write my physics texbuk for sec skul o

[quote author=Doc_Miss]Didn't read it...too Long[/quote]take time to read it and u'll know u've bin making a mistake. Also, u will know its not worth an arguement.

Uzzidili: somethings de too much. You know how many pages ago this learnin start. No body wan agree to disagree. Y'all think y'all re right

oga sorry but dat question don get end now . . .

But dis one wey u wan vex so, i guess u are not a science student. .

exPLIcit7: nofin...0,thank u more mb 2 ur data...

lol . . . mb ko. . data ni. . .abi na how yoruba they speak am sef

Uzzidili: Anybody wey talk about that weight question again go vex me. Make una no worry una go sit down for exam next year. Chill. Una think say na this one wey una de quote reference. Pikins

oga i disagree with you we learn everyday and we musnt wait for exam to come b4 we learn.

Exam test wat we know and not wat we read. . . so if i'm corrected today i wont fail in an exam if they brought the question. . .

Boss99 how u na. . . . ? Na wa o

exPLIcit7: miscellainous you will forever be my best pal on this thread...END OF DISCUSSION...all has been said...I couldn't back it up because they were all attacking me...THANK YOU 4 HELPING AND UNDERSTANDING ME.

baddo. . . U are welcome bro. . .but why u nor con dey for my faculty na ? lol

[quote author=Doc_Miss]Your Last Post Contradicted this One. You clearly stated that the heaviness of 1kg Of sand and 1Kg of Iron Is DEFINITELY Different. When u say DEFINITELY....I'm assuming u meant 'NO EXCEPTIONS' .

And about Density....don't confuse yourself...the guy who asked the question didn't say anything about the Volume.

If I can remember clearly...he said 'Which Is Heavier' ?
Simple Answer : None (assuming g is the same)[/quote]sist good afternoon o. . .i didnt want to join the arguement but, then i thought ''miscellaneous u nor lyk physics ?'' I had to quickly rush and quote ur post cos i think u are really confused and others might think u are right since no one has given valid point.

The question- 1kg of iron and 1kg of sand which is heavier ?

firstly, heavier means which one weighs more (i.e the weight). . . . Wait dont argue!! Lets take time to break the question.

1kg of iron has same mass with 1kg of sand because the ''volume'' might av made it up for sand to av d same mass with iron. . . but when the question says ''heavier'' it bcoms sometin else. We all know dat 1kg of iron is denser than 1kg of sand then, how can one not be heavier than the other ? . . .wait dont argue!! I know u will say: ''they av considered the density before arriving at the 1kg and so they are both equal.''

Now, lets rush down to archimedes principle which states that if an object is partially or wholly immersed in a fluid(water or air) there is an upthrust that is equal to the weight of the fluid displaced.

What is upthrust ? Upthrust is up-thrust. What is thrust ? Thrust is a force. . . So wat is an upthrust ? Upthrust is an upward force!

Now to say which is heavier, suspend the 1kg of sand and 1kg of iron from the same location on the earth and u'll see that the sand produces more upthrust than the iron. . . (hope u know that na)

we all know that the formula for weight is mg but that will only beg the question and confuse u more.

To simplify the whole thing, we say. . .weight= acc. due to gravity - upthrust i.e w=g-u (hope u agreed ?)

g= a downward force and
u= a upward force.

So, g in both sand and iron is same at that point but the upthrust differs and thereby, shows that iron is heavier than sand.


Note=> doc_miss and the rest hope u av seen that many factors shows wen a body is heavier. . .although the acc. due to gravity(g) might be same we dont throw away the concept upthrust . Pls take ur time to study wat i wrote above. Dont confuse ursef with the statement ''mass is constant.'' when they really say mass is constant, they meant take 1kg of iron to miami, dubai, hawaii or even pluto-a planet etc the mass will be same they didnt mean 1kg of iron will not be heavier than 1kg of sand.

Explicit7 and Eng. Tino got a point but couldnt back it up. . .wen i expected both to execute d job jointly.

Thanks.
