dolapo74:
please I will like you to explain .Thanks.

Okay, lemme try


Phase change is a physical process, that is no new products are formed, so it will involve a very little amount of energy.

Most chemical reactions involve the removal of the outermost electron(valence electrons) of atoms. They do not in any way affect the constituents of the nucleus of atoms, so it will involve more energy released than phase Change..

For nuclear reactions, they involve ALL the components of an atom- the electrons, protons and neutrons..
This means that it will involve a much greater amount of energy than chemical reactions and phase changes..

Take for example, the artificial transmutation of N-14 from C-14.

The energy released is about 1.5 x 10^-7 kJ, which is about 100,000 times greater than the energy released from most chemical reactions

dolapo74:
The decreasing order of the magnitude of energy changes is
a. Phase, chemical, nuclear
b. Chemical, nuclear, phase
c. Nuclear, phase, chemical
d. Nuclear, chemical, phase

I never knew hardwork really pays like this.
from 249 to 304
the most of it all was my physics that I had 43 last year,I can't believe my eyes.

Woah

Congratulations Bro..!

ENGLISH.
Fill in the blank space with the correct answer.
By the end of this year,..........in this town for eleven years. (A) I'm living (B) I'd be living (C) I'll live (D) I'll have lived (E) I have lived

..D

DrBESTJC:
The answer is D

REASON:
A marriage between a Rhesus positive man(who may be homozygous for the dominant allele,RR, or heterozygous for the dominant allele,Rr) and a Rhesus negative woman(who can only be homozygous for the recessive allele,rr) will result in the woman having a baby whose chances of becoming Rhesus positive is high.Consequently,the baby's blood will agglutinate(clump or stick together).

Yeah Bro..

You're Correct

BIOLOGY (POST UTME)


Marriage counselling will be recommended for which of the following couples?


A. Rh+ woman and Rh- man

B. Rh- man and Rh- woman

C. Rh+ man and Rh+ woman

D. Rh+ man and Rh- woman

Bobola07:
how was it calculated?

They used UTME, post UTME and O'level results as follows:
Post UTME was over 40, O'level carried 10%:
A1 - 10 points B2 - 9 points B3 - 8 points C4 - 7 points C5 - 6 points C6 - 5 points D7 to F9 - 0 point
Aggregate = UTME/8 + post UTME + O'level

This is what God gave me....
And I made this at first attempt...!

Congratulations bro

Fantastic Result you've got there..!

Its good to be back Long time of jacking Congrats orezy
Me just bag 333 oo Congrats once again it wasn't easy oo

Congratulations Bro
I'm really happy

DrBESTJC:
Alright...



We were three friends in my town preparing for this Jamb.We went to Jamb lessons together,studied together and even wrote our Jamb exams on the same day(Friday last week).


When the results were out,the smartest among us scored 309......now an MBBS aspirant in UNN.
The other guy scored 302.......also going for medicine in UNN.


And........


I scored 303.......going for medicine in UI.(please,pardon me for I cannot upload the picture here...abeg na nokia torch I dey use ...things go better. ).God have finally wiped away my tears after four years of persistent trials,and I pray that the same favour locate all aspirants here this year......


I also saw scores like 340,337,320,328,311,etc.......and I think this is suggesting that the cutoff mark for medicine this year will be very very high especially in schools like UI,UNN,UNILAG and OAU.


Guys what's your take on this.....


I think we should begin early to discuss and prepare for this post UTME now because I can remember that we started very early for this Jamb and many of us here bulldozed and fired an intercontinental ballistic nuclear and catastrophic missiles against the enemy target(JAMB)!!!.


One of the army generals of this forum is Orezy5.......I say a big congrats to you and to others who also won the unprecedented victory against JAMB.

Congratulations bro...

With regard to your question, of course, the cut off marks will be high, considering the scores I've come across, buh all we have to do is to start preparing for post UTME so we don't get beaten at the post

A stream is flowing at 0.75ms and a boat heading perpendicular for the stream landed at the opposite bank at an angle of 30°. Calculate the velocity of the boat.

A. 1.50ms
B. 1.00ms
C. 0.86ms
D. 0.65ms

Please help I need proper explanation.... How can I draw the vector diagram in order to solve the equation.... I have no problem on the solving part just please explain how to draw the diagram



Orezy5... Please can we chat on whatsapp

Okay..

I don't think the question is complete..

Is the angle inclined to the horizontal or vertical?
