Rutherford's alpha scattering experiment showed that the majority of alpha particles fired at a thin sheet of gold leaf passed straight through. Some of the particles passed through the leaf with a small ...

collect x terms together i.e.) 2x - X = 1x and then collect y terms together i.e) 6y + 2y = 8y add your two answers together to get: x + 8y

Answer x +8y

S- specific M- Measurable A- Achievable R- Realistic T- Time bound

The phrase "a and b are roots of 2x^2+6x+7" is just a way of saying that x=a and x=b solve the equation 2x^2+6x+7=0. Check out that by diving by 2 on both sides of this equation we get that that...

The key to analysing a primary source is remembering what it is; it's a source from which we want to get useful historical evidence. But, if it is a primary source, then we must remember that it is comple...
