Power stations use step-down transformers to decrease the voltage of the electrical output. The power lines have a constant resistance (say, R Ohms) which means there is a power loss across the lines give...

The kinetic theory models gas particles as points moving around with a given velocity. Heating the particles causes the transfer of heat energy, which is then used to increase the particles kinetic energy...

We can check for the presence of non-reducing sugars the Benedick's Test. If a reducing sugar is present in a solution, adding Benedick's reagent and heating will form an insoluble red precipitate. Non-re...

Being a doctor is a difficult job and requires more skills than just being good at biology. Medical schools are looking to see if you have these skills and that you understand what you're getting yourself...

Differentiate y to get: dy/dx = 7-3x^2 , dy/dx = 0 , therefore x=(+/-)sqrt(7/3) d^2y/dx^2 = 6x , substitute x values in to y=7x-x^3 and d^2y/dx^2 to find coordinates and the type of the stationary point.<...
