An increase in temperature increases kinetic energy of particles, so collision frequency increases and more enzyme-substrate complexes are formed, therefore rate of reaction increases. The rate of reactio...

Electronegativity increases across a period because the atomic radius decreases (i.e. the valence electrons are closer to the nucleus and experience a higher attraction). This is because there are more pr...

Kepler's third law states that the square of the period of any planet is proportional to the cube of its orbital radius.To derive it, two equations are required: F=GMm/r^2 and F = mv^2/r. These are Newton...

First, if k=0 then the equation has no real roots since in this case we would have 5=0 (this is a proof by contradiction).
A quadratic equation of the form ax^2+bx+c=0 has no real roots if the discri...

The process of synaptic transmission is when electrical nerve impulses, known as action potentials, travel from the dendrites of the cell (the receptor site) to the axon terminal. When these action potent...
