But even in shm, it is called angular velocity. I have never heard of angular frequency b4. We keep on learning sha.

when angular velocity is measured in rev/s (revolution per sec), it can also be called Angular Frequency but when it is measured in rad/s, it is strictly called angular velocity.

Pls House! What is the formula and dimension of surface tension and tension? Explanations will be appreciated.

The unit of surface tension is Nm-¹

where N is newton , and m is metre

Newton is the unit of a force, F, and F = m × a

where a is the acceleration and m is the mass

F = kg × ms-² = kgms-²

That is, newton equals kgms-²

Nm-¹ = kgms-² × m-¹

= kgs-²

which in dimension gives, MT-².

The unit of tension is the same as the unit of force which Newton = kgms-²

in dimension, that is , MLT-²

They would open it for u to apply...it sometimes happens that way...Relax ur mind, every kobo u pay to UI is safe...

Not every kobo is safe oh

Abi , is it not UI?

kingtunde:
Yeah, i have paid my hostel fees

I thought a room should have been assigned to you before the payment or it is not so again?

Alienwrit3r:
This one dah all of you are talking and arguing about resumption, shey den don clear all of you ni, cos den still never clear me oo...

me sef just dey look them with one eye.

Isrkay:
when I haven't been cleared

Ibadandentist:
It is on the portal
And get ready for everyone to fight against this

Fight what exactly?

anonymous2001:
Someone called the admissions office and they said they're having some technical issues but it should be sorted out this week

Always having technical issues

Who be Mr. OKiro?

sighs ...

UI, our school..

syncACE:
paid?...wey the money sef?...
Tho person go still pay am last noni

No be their faults sha.
Na UI dey ask for rubbish

syncACE:
Health centre requests for 7k
7k for a piece of paper

They are thieves !!!!..
you paid?

Please guys how can I draw the vector diagram fro this question... I rilli need help in drawing vector diagrams

A weight of 20 newton hangs from a fixed point by a light inextensible spring. It is pulled aside by a horizontal force with the string inclined at an angle of 30 degree to the vertical.The tension in the spring is.

The diagram will be in a form of a right angled triangle.
Let assume the point the newton hangs from be A, Draw a line vertically downward from that point to another point B. The force is being applied at the point B which makes the newton to move horizontally to the left side, draw a line from point B to another point C, then join AC which indicates the line in which the tension acts, Angle BÂC is the angle in which the string makes with the vertical.

Now, from your diagram, since the tension is acting in the hypotenuse side, you resolve it to the vertical which gives Tcos@ where @ is theta, and since the body is at equilibrium, upward force equals downward force.

Tcos30° = 20

T = 20/cos30

T = 20/(√3/2)

T = 40/√3 or 40√3/3N.

wow......we even have the same name
your name is samuel right?

LOL.
Yeah, it is.

sammycranebaba:
Any newly admitted physics student¿

There is.

Temilistic22:
U can start your clearance online 24hrs after you pay your acceptance fee at the cyber cafe. There's no particular venue and date

... and this info was gotten from?

Coa123:
something aint clear to me,i have been offered admission on the u.i portal but my status at caps still remains "sorry, no admission given yet"...can someone tell me what's up 'bouh this??

Since you've been admitted on the UI portal, just calm.
The CAPS will change very soon, I believe that is due to the incapacity of JAMB.

Congrats.

Etihadstore:
There was a website called nairaland.com

Now Known as BBN.com

... and how does this in any way help our country current situation(s)?

Person wey snap this thing get mind oh

Not surprised tho.
It's now becoming a common thing.

jboycoded:
so how things now na?

We thank God, let's talk on WhatsApp.

jboycoded:
boss no be so oo.everything just dey somehow.

Hehee, no problem sha.
God bless our efforts!

jboycoded:
sir jendoor I hail oo.long time.

Yes boss , you just forget me like that...

deefrosh:
No problem with not picking chemistry?

At all.
English Language, Mathematics and any of the following subjects: Biology, Chemistry, Physics, Further Mathematics or Geography

deefrosh:
I picked maths eng phy and biology for jamb..I'm I safe

Yes sire, you are absolutely safe!

Rubbish!!

so?
what should we do?

jboycoded:
yeah made mistake when typing, number is 081. thanks man.

Boss
