cohesion is an intermolecular force between molecules of the same kind. E.g Hydrogen bond between water molecules,hydrogen flouride.

cute.....grab this.....how can a polarized light be detected?

taiocol: Near the surface of a planet
the gravitational field strength is
uniform and for two points 10m
apart vertically , the gravitational
potential is 3 Jkg^-1.How much
work must be done in raising a
mass of 4kg vertically through
5m?

Karleb: aunty mathemagician we need ur workings

Karleb: no come dey form big man for here, make u contribute o.

ChocolateBarbie: (Y)

Ai-bi-ke:


u tried bro....buh try it again cos u are not yet right

ChocolateBarbie: In the laboratory preparation of oxygen,maganese (iv) oxide serves as _______?

ChocolateBarbie: lol lee mi jor

Karleb: so na wuruwuru to the answer u do, God don catch today.

mgb4reel:
from hooke's law
f = ke
=> 5 = k * 0.01
=> k = 500N/m
Given 20N, e will be
e = f/k = 20/500 = 0.04m
Therefore, the length of d spring = original length + extension
= 0.5 +0.04+0,01 = 0.55m

ChocolateBarbie: lmao tz brain solvin' o

shakur07: Baba no time I was a very active member during d last session ..I can jes chip in sum idea for yhu guyzzzz

Karleb:
Catalyst.
1. What is isomerism?
2. List the types of isomerism?
3. Define estirification?
4. What is polymerization?
5. List the types of polymerization?

Karleb: brain solving? Tell me about it

ChocolateBarbie: A force of 5N extends a spring of natural length 0.5m by 0.01m. What will be the length of the spring when the applied force is 20N?

Ai-bi-ke:
Bro I wont av much tym to solve daht xo I wil copy and paste what u did and re modify it sir..xo dat u can grab ur mistake...i think daht helps sir

mgb4reel:
@ai-bi-ke, pls read tru d question again. Y did u add d initial extention given in d first statement? D first statement only gives d necesary info to calculate d elastic constant or stifnes of d spring.

Mikebis: dis are ss3 wrk jawe,i lv am 4 anoda persn
nb:i no fumble o

ChocolateBarbie: wat are yu feelin' lyk now??

ChocolateBarbie: 1] Isomerism is the occurrence of two or more compounds with the same molecular formula but different molecular structures.
2]

Mikebis: lemme help u with d rest3.geometric nd optical isomerism
4.d reactn btwn organic acid+organic base->ester nd water e.g alkanol+alkanoic->>alkanoate+water,d alkanoate is knwn has ester

Ai-bi-ke:
hmmmn!..

Mikebis: walai,i no wan enta b4,buh as i c u,e b like say me2 go log in o
