Yeah Bring on the Watercooler...Mr.Spidey you have been awarded a lifetime supply of watercoolers so you can enjoy every summer for the rest of your LIFE

buahaha...make sure they are filled..

 

[screamingskull]

buahaha...make sure they are filled..

Us ke liye you will have to ask Nestle or any other company
My job was to provide you with the coolers, break as many and get another

umm...k...lets not drag the joke alright..

Yeah I am tired of this too!!

Yeah I am tired of this too!!

so you now wanna brag about getting a silai machine??

 

[khizer shahab]

is there any difference b/w centipetal force and centrifugal force??

hahahahaha I can't stop laughing at the thought.
You first

 

[Spidey21]

the centrifugal force is totally opposite to the centripetal force....

 

[Spidey21]

nah i got the water coolers...silai machine is for you..

 

[khizer shahab]

oh i dont know centrifugal ones please explain??

 

[screamingskull]

Centripetral force is the force that causes an object to move in a circle, this force is acting towards the centre of the circle
Centrifugal force is the force acting outside the circle and causes the object to move away from the centre of a circle

Hope this helped

Thankuoy Thankyou
I am indeed honoured

 

[Spidey21]

Thankuoy Thankyou
I am indeed honoured

LOL..
so when do i get you my torn pyjamas?

 

[Spidey21]

Centripetral force is the force that causes an object to move in a circle, this force is acting towards the centre of the circle
Centrifugal force is the force acting outside the circle and causes the object to move away from the centre of a circle

Hope this helped

you have proven yourself worthy of the silai machine!!

 

[screamingskull]

yayayaya

 

[Spidey21]

now we are going off topic..
can anyone tell me how to do this...

Water at a temperature of 16 °C enters an ice-making machine and emerges as ice cubes at a
temperature of –5 °C. The melting point of ice is 0 °C.
(a) Calculate the total energy removed from 1.0 kg of water as it cools from 16 °C, changes into
ice, and then cools to –5 °C.
specific heat capacity of liquid water = 4.2 × 103 J / (kg °C)
specific latent heat of fusion of water = 3.4 × 105 J / kg
specific heat capacity of ice = 2.1 × 103 J / (kg °C)
energy

 

[Spidey21]

suggest why less energy is needed to change ice into water than to change the same
mass of water into steam
this too

just suggestion it is due to in solid state the bond between molecules are not much stronger than water in liquid!!!

are you sure??

 

[khizer shahab]

are you sure??

nopes !!!
