a typical question would be a setof parametric equations y(t) and x(t), asking you to find dy/dx and then the tangent/normal to the curve at a certain point (ie t = 2)

this question is a great example as we have many different aspects of a level maths workng together into one.initialy you will use use chain rule to find dy/dx = dy/du * du/dx.then you will either keep the v...

Calculate the root mean squared speed for 16g of oxygen gas at 50(deg Celsius) and explain why we use this instead of the average velocity of all the particles.

Root mean squared speed is given by v(rms) = (3kbT/m)^(0.5) = 501.68. Student should show how to calculate the mass of each particle (m = (0.016)/0.5(6.01x10^23)), convert degrees celsius into kelvin and und...
