Hi I am doing homework for science and I'm stuck it has to be in tomorrow (tuesday) and I don't know what the following things do
Relay switch
Thermistor
Magnetic switch
Moisture detector
Any help?

I don't know what they do either. Don't you have a text book so you can look them up in the index and maybe actually study what they do? Better get hopping!

Did they not teach you this already? Is there a text book where you can look them up?

Must be an echo in here

No text book grrr haha

Haha yourself, why no textbook ?

They don't let us take one home

All of those are defined by using Google. Do you know how to find definitions?

But you have internet access and Google is a wonderful tool. We aren't allowed to do your homework for you.

I know but I can't seem to find the right answer any way it don't matter now I'm ill with tonsillitis (however you spell it haha) I'm finding it hard to swallow grrr

If you can't find the right answer, how do you expect us to? We don't know what your study guide says.

Either way, we are not allowed to do your homework. The most we can do is assist in editing what you have already done.
