2y 1/2 -7y 1/4 + 3 = 0 We need to use a substitution to obtain a quadratic.Let y 1/4 = x (use the y with the smallest fractional power as your substitution)From this, we can see that y 1/2 = x 2 (using the l...

The sliding filament theory demonstrates how the muscles in our body contract. As a signal reaches the neuromuscular junction (motor end plate), neurotransmitters such as Acetylcholine will diffuse across th...

The product rule states that if y=uv, where u and v are both functions of x , then dy/dx = u(dv/dx) + v(du/dx) Therefore, the differential of 2x e 3x can be found by letting 2x= u and e 3x =v . u= 2x, du/dx ...

Structure of the protein is easier to understand if we start from the beginning and gradually build up our knowledge. Firstly, proteins are made of amino acids. Each amino acid is made of a central carbon at...

To explain this I will use a made up example question: A 2(g) + B 2(g) <-> 2AB Change in enthalpy= Negative remember: according to Le Chatlier's principle, if a system in equilibrium is subjected to ch...
