can anybody help me with my science homework ?
You have to " Use detailed particle diagrams and the big idea of energy transfer to explain how the ear defenders work"
Also, we have to draw a picture of the ear defenders and describe all the bits of it. But I've done all that, i just need help with the Big Idea Of Energy Transfer Idea .
It Hass To Be In Tomorrow, PLeaase
From what I can read on the web, The Big Idea of Energy Transfer actually is Einstein's equation E = mc2. Much as been written about it; the following is one of the most general accounts that I could find. I hope this helps you get started. Read the article, then extract the ideas you need to make your report.
something about sound waves vibrating against each other.... if its scattered about like in air they can't vibrate properly and send energy to each other i have the same project as you do.
Energy transfer is when the sound energy converts to heat energy on the ear defenders.
