@Horlarmancy, you see, you guys have to take things lightly...either of you should have probed to know who the man behind the Mask was. But you were blinded by seemingly irrelevant things like words...

Good afternoon and Happy Democracy Day!!!

P0lyMath:
@Horpeyemmi66, u tried for the other questions though u re more than it. But that No2 is a big NO.


@Thaotech, u tried wella bro but u need to be conscious of what a question wants(0.32N=320g)


That no2, really puzzled me before I could solve it.



FIGHTING

thank you. About the 320g to Newton

320g to kg divide by 1000 = 0.320kg

0.320kg to newtons multiply by 10= 3.2N

once again gracias bro.......constructive criticisms pls

P0lyMath:
1. A body of mass 10kg in equilibrium by two ropes. If one rope pull the body horizontally and the other at 40° with the vertical, calculate the tension in each ropes.

2. A stone is dropped from the top of 50m high tower. At the same time another stone is thrown upward from the foot of the tower with a velocity of 25m/s. At what distance from the top and after how much time the stones cross each other.

3. The uniform metre rule balances on a knife edge at the 55cm mark when a mass of 40g is hung from the 95cm mark. Find the weight of the ruler



FIGHTING

1. T1= 84.0
T2= 130.5



3. 3.2N

horpeyemmi66:

hahahaha!....but you amazed me, you were so close, very very close; and I think that is very Laudable.

You will see how close you came before you can spell JACK ROBINSON...lols

I want to clarify something before delving any further,
for the general salt AaBb:
Ks ↔ [aA^b+]^a x [bB^a-]^b

Now to no 1....
PbI2↔ [Pb^2+] x [I^-1]
Ks↔ [Pb^2+] x [2I^-1]^2......(**)
Ks↔ [1.65 x 10^-5] x [2 x 1.65 x10^-5]^2
Ks↔ [1.65 x 10^-5] x [3.30 x 10^-5]^2
Ks↔ [1.65 x 10^-5] x [10.89 x 10^-10]
Ks= 17.96 x 10^-15
Ks= 1.796 x 10^-14

One might wonder where PrOton got the unit to his answer which is very correct, here is what he did:
Concentration is measured in Mol dm^-3 abi?

So putting Mol dm^3 in place of Pb and I2 in (**),
K= [mol dm^-3] x [mol dm^-3]^2
K= [mol dm^-3] x [mol^2 dm^-6]
K= mol^3 dm^-9

Therefore,
Ks= 1.796 x 10^-14 mol^3 dm^-9.

Cc PrOton, you didn't multiply your Iodine ion by 2

2. This is rather explicit needless to say
SrSo4↔ [Sr^2+] x [So4^2-]

If you follow the format of the general salt above AaBb, in this case nothing changes, ipso facto I mean you don't need to square or multiply any of them in the Brackets[].

So, Ks↔[Sr^2+] x [SO4^2-]
3.2 x 10^-8= [C] x [C]
C^2= 3.2 x 10^-7
C= √3.2 x 10^-7 mol^2 dm^-6
C= 1.79 x 10^-7 mol dm^-3

cc PrOton, your standard form notation was not same as above lolz.


Nevertheless, you guys have done well. Kudos to Mikechibuzor, thaotech, PrOton.

But PrOton,

"256y5= 3.2 x 10-7mol2dm-6
y5= 3.2 x 10-7/ 256
y = 5√1.25 x 10-9"....this is abracadabra take the 5th root of the unit and see what you get.

And that last fracas, you sef no be pikin again, let it go.

seen my mistake....gracias

*CHEMISTRY

1. Calculate the solubility product of lead iodide at 25 degree celcius, given that its solubility at this temperature equals 1.65 x 10^-5 mol/dm3

2.Given that the solubility product of strontium(II) tetraoxosulphate (VI) at 25 degree celcius equals 3.2 X 10^-7 mol^2 dm^-6, Calculate the Solubility at this temperature.

Woah!, its great been back here again...I was forced to go on a Sabbathical by PHCN.

I would go laconic now, brevity is beautiful.

@Bhuumhite, am gunning for Physiology dear, hopefully am gonna leave that department in the fall of 2016.

@Seunvense, your addition was duly noted; ref: "MBBS Students will do all of this excluding BOT174"

@DrHost, baba I don dey miss you ooh!, wetin man go do...

@Cassyrooy, "Ojukwu is dead but his manhood lives on", (quoted from Words on Marble by Mrs. Jonathan)...I guess Ojukwu had too many wives.
Cc Sir. thankyouJesus...stop officiating his weddings!

@Mikechibuzor, your plight shall be looked into by Sir. PrOton. I like your style of approach but you jumbled up some parameters.

@Polymath, the "FIGHTING-CROONER", how have you been, I know you must be doing great!...you ALMOST dealt with my question, nevertheless.

@thaotech, thanks for attempting the Physics question, you actually amazed me.
----------------------------------------------
Solution to the Physics question.

i) for the 4kg mass moving downwards: 4g-T=4a..........equ 1
for the 3kg moving upwards: T-3g=3a.

After you do the simultaeneos abracadabra, your a=1.43m/s2(common acceleration)

ii) Their speed after 2 seconds
v=u + at
u= 0, body accelerating from rest
a=1.43m/s2
therefore. V=0 + 1.43x 2
V=2.9m/s

iii) The distance each travelled in two seconds:
S= ut + 1/2 at^2
S= 0 + 1/2 at^2
S= 1/2 x 1.43 x 2^2
S=1/2 x 1.43 x 4
S= 2.9m

Post Script: @Dapo777, your advice has been laudable and I really appreciate it. People are jacking, obviously...instilling fear with the words"ui will only pick the best, post ume is like a war" you use aint helping matters!

I filled with trepidation by pessimists when I wanted to write common entrance, Junior WAEC, Senior WAEC, JAMB, Pre-Degree test and FinaL Exam....guess what?...I ed all of them exceedingly well!...U.I is not gonna be an exception for me or anyone on this thread by the Power in the name of Jesus. #Constructive criticism please.

cool boss

*PHYSICS
A Light inextensible string es over a smooth Pulley and carries masses of 4kg and 3kg at its ends, the masses are released from rest,
find:
1. Their common acceleration
2. Their speed after two seconds
3. The distance travelled at that time(Take g=10m/s^2)

You welcome Bhuumhite, what course?
