No it does not. In some cases friction can cause motion. To illustrate this we will consider a body M₁ of length L placed on a frictionless surface and a smaller body M₂ placed on to...

This is a great question. In order to answer it, I would first think about my thesis (line of argument), because the question isn't only asking how Priestley explores the theme of social class, but also w...

√(6²+8²)=³√125a³√36+64=5a√100=5a10=5aa=2

Where we are given two equations that equal the same thing we can substitute one into the other e.g. (1) x² + 3x + 10 = y (2) 4 - 2x = y. Sub (2) into (1) - replace y in (1) for (4 - 2x): x<...

To answer this, you need to try and remove on of the letters from the equation. You could multiply the first equation by 2 so that the number in front of the y's are the same in both equations, with 10x+2...
