yup. A fridge uses the radiator at the back of the equipment to radiate heat away from inside the fridge. The heat transfer makes the inside of the fridge cool, but using coolants evaporating at much lesser than boiling point of water, normally coolants evaporates around 5-10degC, that runs through tubes inside the fridge to outside the fridge.

The heat that is taken off from inside the fridge by the evaporated coolant, then cools down and precipitates back to liquid to flow back. The outside hotter fluid is cooled by fans on the radiators.

Thus when you open up the fridge, the room will not be cooled, as the front side of the fridge gets cool, but the back side of the fridge gets hot. In fact there is no change in overall temperature of the room. For more advanced part, since there is no 100% efficient systems, most probably, you will get a “hotter” room by opening up the fridge door, as the regulator pumps up the needed electricity to try to cool the whole room at higher temperature than the chamber.

Same for aircon.

maybe the students doing social work, help Ah Gong, Ah Pek cross the road, sell newspapers, clean their house leh?

duh!

maybe she got itchy armpit?

I actually more interested in selling my desktop now…

But looking at what new stuff is available in the market now…in terms of specs.

Thanks, Kenneth!

Waiting for your replies.

Urban, its a HT Core, E-series (i.e. extreme)

Remember the evolution of Intel chips….

P3==>P4==>Pentium D (dual core)==>Pentium E (high speed) > Core duo > Core 2 duo (much lower speed – but 2 processors)

up!

Price negotiable, if you are close to NUS, can schedule for a meetup to have a look at PC also.

I've got some questions that require some assistance from you guys. Appreciate your help.

 

1. You walk a distance of 2km at an average speed of 6km/h. You then run for a further 10 minutes with an average speed of 12km/h. What is your average velocity for the whole journey?

 

My answer's 8ms-1. Please check to see if you end up with the same as mine. If not, please highlight my errors. Thanks.

Average vel = total dist/total time Total dist = 2000m + 2000m = 4km Total time = 2/6hr+ 1/6hr = 20min+10min = 30min Average vel = 4/(1/2)=8 km/hr

 

2. A Toyota Corolla starts from rest and accelerates at 1.5m/s2. After what time would its velocity be 20m/s?

 

I'm not pretty sure about this. But it should be something like 13.3333 secs when you divide 20 by 1.5? Or is it not?

 

3a. When a velocity is increasing, acceleration is _______

I wrote increasing

Wrong! When a velocity is CHANGING, acceleration is NON-ZERO. Thus, when a velocity is increasing, acceleration can also be a positive CONSTANT or an increasing value.

 

3b. When velocity is decreasing, acceleration is ____

I wrote decreasing

 

3c. When the velocity is constant, acceleration is ____

I wrote zero.

 

Thanks for your guidance.

 

 

shade, graduating liao or not?

Should have ask me to go along mah....

but hor....you so rich....pay abit more ok lah....kekeke...

Great!!!

its the single most important feature in Sgforums!

Vit P, you should send thread to Aunt Agony thread, not chit chat lah...so now everyone is chit chatting.

Happy Birthday LS!!

A boy , A, found a cockroach . He kept it in class and I purposely TALK loudly to A . that let put the cockroach to that B (China gurl's bag) .. A said don't want and we never really talk about it ...

 He said : what if teacher find out ..

I said : Just say the cockroach fly to her back lor ..

Then we never talk anymore liao..

It is until the other person , C and D came , they are playing with deordourant and just nice , they hated that B so they ALSO SUGGESTED to put that cockroach into B's bag WITH REAL INTENTION !

My talk with B is just some causual remark ..

But worst lar , B go listen to C AND D and put that cockroach into her bag.

There were a few others in the class now , I am going to ask if they heard anything , suggested by C and D anot .. I am trying to find these witnesses ...

Do you think it will help ? Let's take it that I am telling the truth right now ... What do you people suggest then ?

 

Again, you should have told the HOD about the other 3-4 guys. Why you didnt? Did you not think of that? Because, you also scarred later they other 3-4 guys coming after you? You are not being righteous also.

If you have told the truth about the other guys what they do, it clears up everything at the first moment, and will also allow the other guys C & D to learn from their mistake. Do you think now that C & D will learn from the mistake  being that you are the one who is the scapegoat and bare all the punishment? hahahah...

This is what had happen today.

-My friends put cockroach on her SHOE , in her bag and spray de-ordourant at her items

Serves you right for not helping her out by telling on your firends! 

Gong Xi Gong Xi!
