A heating coil of resistance 30ohm is connected to a 240volt supply for 300seconds to boil a quantity of water in a vessel of heat capacity 200j/k. If the initial temperature of the water is 20degree celsius and its specific heat capacity is 4200j/kg/k. Calculate the mass of water in the vessel. (answer=1.67kg. Please solve until you get this answer)


2. A transformer is required to supply 0.2ampere at 100volt from the secondary using a primary voltage of 250volt. if the primary has 120turns, calculate the number of secondary turns and the primary current assuming the transformer is 100% efficient.(answer= 480turns, 0.8ampere. pls solve and get this answer) cc indomixx eben331 drbestjc aceed

. I keep getting 1.71 for number one. Dunno, where I'm getting it wrong.
2. I got 48 instead of 480 and 0.08A instead of 0.8....

BiafranDel:
okay bro. I will call you when i get to school on wednesday.

Aiit man... #Peace

BiafranDel:
@indomixx i have talked to the guy. He said he can only buy one because of cash. That means when you get to school on tuesday, i will give you his number so you call him. You give him the cash, he will help you get it that tuesday. The price is 500.

Okay boss. Thanks a lot.
Hope we can see when I arrive??

BiafranDel:
I dunno yet. Tuesday or wednesday. If i finalize with the guy, i will let you know before then.

Okay, thanks man.

@indomixx solving without calculator no be child's play o.
Forget all those easy tricks. Solving when reading at your comfort is different when in the exam hall proper.

I tried to time myself today and see how fast i can solve. Omo i spent almost five minutes to solve just one question on molar concentration and gas laws on past question.

I called one guy that wrote for sciences last year, he said his friends used that wristwatch that has calculator on it and they were able to finish all their questions in time. He said its 500. Let me know if you are interested. That's just the best option for me.

Of course, I'm interested. We will see in school there. When are u travelling??

BiafranDel:
Drop your number bro. The one you gave me before ain't going through. Cc indomixx

Unfortunately unijos don't conduct post utme but screening. Pls u suggested that I have 95% advantage in UNN, can u be more elaborate (clarify) because am from Nasarawa state and can one do change of institution twice? I have earlier changed from unilorin to unijos
................I appreciate

Considering the state u came from, u stand a chance because in UNN every state under ELDS always has a lower cut off compared to other states. For example people with aggregate of 260+ from Northern states like Bornu, Nasarrawa were admitted into medicine reason being that there are no much applicants from that state and they are seen as educationally less deveoped states.... In fact I saw someone with an aggregate of about 230+ from a core north admitted into medicine last year(I know cus I applied the school last year, so when the list came out I went through all the names in medicine)..... Regarding the change of institution. Yes, it can be done twice but sadly UNN is starting PUME on the 23rd(tomorrow),so portal for registration portal is already closed. Nonetheless, remove negativity from ur mind. u can make it anywhere so far u are determined. 279 is a pretty nice score if u ask me.

JoeNafty:
Pls I need help, Iam aspiring for MBBS in unijos and this is my fifth attempt! I have 279 in jamb; 2B3, 2C6 & 1C5 in my o'level and am from Nasarawa State. Do I have any good chances of securing admission this year? Your comments are much welcome pls

If I were u, I would have applied for UNN. U stand 95% chance there with ur score. Good luck though. U still stand a nice chance in Unijos. Just go and kill the post utme.

Exam is just 8days away. God help all of us here oo. God, Pls grant our efforts with success, no one here will write jamb again. As we are going for the exam, success will be our portion. Only what we have read will come out on the day of the exam. God, as you have made us to reach the minimum cut off of 200, so shall we meet our departmental cut off. There shall be no error on the day of the exam. Thank you Jesus, because I believe you will do it for us all. Amen. IJN

The Ekiti people have with these results shown that they are educated and cannot be tossed around like grasses in the wind. Four years ago they went back to Egypt but today they are out of Egypt on the way to the promised land. Thanks to Ekiti people for collecting Eleka Olusola and Fayemi 's money and still voted according to their preferences and consciences. The money you all collected is our money. Spend it as you like. It is glarring that Fayose and his tatalong Eleka have lost the goodwill of people who are yet to see communal development they desire and effects of good governance on the masses. Ekiti with people cannot be deceived with stomach infrastructure again. Fayemi the governor elect should use his good intention to put smiles on Ekiti people. To whom much is given much is expected. I rejoice with the winner and sympathise with the loser. Thank you Ekiti .Thank you all the masses in the state. Thank you all the civil servants. Thank you all the youths and students. You are welcome to the promised land flowing with honey and milk.

Have you done your reg?

No,i haven't. Seriously if u ask me what I'm waiting for I won't be able to explain. Will soon buy sha. Next week, certainly.

What is the tension in the cable holding
a mine of mass 600kg and volume 0.8m^3 to
the sea bed, so that it is totally submerged.

What is the upthrust on a body which displaces
0.6m^3 of water, 0.5m^3 of methylated spirit?
(density of water = 10^3 kgm^-3, density of
methylated spirit = 0.8 x 10^3 kgm^-3 and
g = 10ms^-2)

A body of mass 700g hangs from the end of a
long wire fixed to a high tree. A horizontal
string attached to the body pulls it until the
wire is at 30 degrees to the vertical. Find
the tensions in both the string and the wire.

A block of material of volume 20cm^3 and
density 2.5gcm^-3 is suspended from a spring
balance with half the volume of the block

Confirm the correct ones and wrong ones. So I can explain the ones that are correct. Then we can work together to get the wrong ones done

BiafranDel:
@indomixx thanks bro. Knowing all these things will really go a long way in passing the exam.

But for the other part, dividing a small number with a big number. Like 3/20. 2/9. Under these condition, i suppose all the answers are to start with 0. being that a smaller number is dividing a bigger one.
Throw more light on this please.

3/20.
It becomes 0. Then add the 0 to the one on top. It becomes 30/20.... From there u can get it easily

BiafranDel:
@ indomixx nice one thanks. Please for the division. Just explain how to divide a small number with a big number easily like 28/84, dividing decimals like 0.002/0.003, 16.09/0.03. Sorry for taking your time bro.

For the first one 0.002/0.003... What u have to do is similar with the multiplication method. Now count the number before the points. 0.002. we have 3points. likewise 0.003 we also have 3points. Now the 3points above will cancel the 3points below.... We can now say we have 2/3(since the points have cancelled each other)... I guess it will be easy to divide from here..... Right??
But wait!. What if the points are not equal. For example 0.003/0.02.....Now we have 3points above but just 2points below. Now, the one above has one point more than the one below. we have to cancel points. The one above becomes 0.3 while the one below is 2.(This is because the one on top has 1point more than the one below). So, it becomes 0.3/2. Now we still have to eliminate the point in the one on top. To do that u add a zero to the one below(Note, if had it been the one on top is 2points more, we would have added to zero). So, it becomes 3/20. I guess it becomes a lot easier to divide now??..... If there's any part u don't understand, Pls do well to let me know. Thanks
For the other one it becomes 1609/3

BiafranDel:
Thank you. please do. Especially that of division. Doing long division is just confusing.
If you can share any link where i can read it online, that will be
more helpful.

Do you stay in benin?

For multiplication, this is how u can do it. For example 1.5 X 1.5... What u should do now is assume there is no point and multiply straight, meaning 15 X 15 which is equal to 225. Then u introduce the point back to it. Now look at the numbers u multiplied. 1.5 X 1.5. How many points do we have there??... U can know by counting the numbers that come before the point starting from the back. That is start from the 5. The first 1.5 we have only one digit before the point so u take it 1point. Likewise the other 1.5 we also have one digit before the point so u also take it as 1point. After everything add the points. That is 1point+1point which is equal to 2points. Now bring back the number u multiplied which is 225. Now move the 2points u got starting from behind that is from the 5. U will have 2.25... Which is the answer.
NB. If we have something like 3.22 X 1.5. The total points are 3. 2 from the first one(3.22) and 1 from the second one(1.5)...U can then remove the points and multiply and later introduce the points. Hope u grab sha. Pardon me I'm not a good teacher..... Division comes up later

Does anyone knows anywhere I can get DANDY ENGLISH?

U can get it in Uniben. I even need to buy it too. Will go-to the school to get it soon.

BiafranDel:
Uniben does not allow calculator. And some questions still appear in decimal forms.

There are short tricks in calculating(multiplication and division) decimals even in base 10.

If you know the short tricks. Kindly share here.

Cc; indomixx drimmaculate

There's a method I use that works perfectly for me.... Will share later.
