Im trying to get my head around a question in a book as i thought it would be good to give them ago as I am struggling.
The question is:
Explain why a metal plate does not lose its charge when;
a) the plate is + charged and illuminated with visible light.
b) the plate is - charged and...
Well I am tired now, but I've taken on board everything you two have suggested. I am going to go sleep on it and have a crack at it in the morning. I've printed off what both of you have said and will work upon it.
Thanks a lot and ill report back tomorrow with any results
**are these kind of...
I don't have the mass, just the densities of each metal that combine to make the alloy.
No I am not going into this half heartidly, I've been sitting here since half 3 and its now nearly half 9, going through these 2 questions, and i keep comming back to the beginning, why did i take physics...
geeze i feel really thick:frown:
would one cubic metre of the first metal just be 10,000 kg and then one cubic metre of the second metre would be 7,200kg?
so you add them together to give you 17,200kg. But the density of the alloy is only 8000kg/cubic metre.
well i haven't done anything on them, i keep trying but nothing seems right. Weve been told the formula to use throughout these questions p=M/V but i don't know where to start, if someone could point me in the right direction i might be able to get it
with the liquid one, we haven't done...
Once again I've left homework to the last minute so my teacher will moan if i go ask him tomorrow morning. I've scanned the net and all my textbooks but can't seem to find a working example that helps with what i am doing. Could someone look at these 2 questions and help me out?
1. An alloy...
