Newton's second law of motion is F = ma and his law of gravitation is F= GMm/r^2.g is the acceleration of free fall and can be substituted for a, F = mg.We can therefore see that g = F/m and can use that ...

This quadratic equation is in the form ax^2+bx+c=0 (a=2, b=3, c=1), where there is a coefficient in front of X² term. First we have to multiply a and c. we then have to find two numbers z and y...

Lets use an example:Fe³⁺(aq) + e^- <==> Fe²⁺ (aq) E⁰ = +0.771 VLi⁺(aq) + e^- <==> Li(s) E⁰ = -3...
