Physics Coursework

[old.UKTwister]

ok the brief introduction of the coursework:

My aim is to find out if increasing the current, increases the strength of an electromagnet. - which it does

So, for my prediction i have put yes it does.......... but why does it?

Also i get mixed up between these terms so could one kind person please help me with these:

Control Variables

Dependant Variables

Independant Variables

ta

Ok, first off; DO YOUR OWN HOMEWORK.

The basic reason that an increase in current increases magnetism is that more power is available to line up the domains in the metal. More in alignment = a more powerful magnet.

Dependant variables are the things you are checking in the case you've given, the dependant variable is Electromagnetic strength (the units for which I can't remember for the life of me, possibly Gauss). The independant variable is the thing you are changing to affect the dependant variable. In the above example it's current. Control variables are things you keep constant. In the above example one would be voltage.

thankyou very much!

not my fault the teacher is past its sell by-date

 

[lecter]

As usual school teaches you everything arse about face.

Things to remember.
1. A moving charged particle is what creates a magnetic field.
2. The rate of moving charged particles is the current (I=Q/t)
3. Magnetic fields are measured in Tesla.

And they say the nation's youth is going to pot.

 

[Nozzer]

Maybe the time that should have been spent on the homework was spent on pot and as such the homework ends up here.

Winnar.

 

[kameleon]

Maybe if he went to pot more he would be able to concentrate on his lessons better

Someone could do my presentation for this week.

Pls?

It's 'Parallax' by Nanacy Cunard.

Pretty pls?

I'm trying to write a paper on the effects of hyperglycaemia on expression of PEDF and bFGF in cultured endothelial cells but my control genes seem to be affected by glucose too, can anyone help?

 

[Clowneh!]

and all i did was chop up locusts




:E

 

[dysfunction]

I find my Jeans get affected by glucose when I spill coke on them...

Teh study help forum this ain't

 

[Munkey-]

heh. good luck matey. i did my physics coursework last year, some shit about paper helicopters and height. load of old bollox.

still have to do meh Biology Coursework redraft. Chemistry teacher doesnt want us to have our chem coursework back (the cunt)

History coursework is easy, ICT is a bast, maths is a bast (ta dimey) and so was the geography coursework.

Try treating with MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide)

watch for the colour change

You know schools aren't what they used to be when people start putting their homework on the BarrysWorld forums
