Damping reduces the amplitude of oscillation of a system over time. Critical damping reduces the amplitude of the oscillations to zero in the shortest possible time, returning the system to the equilibriu...

The atoms are composed of a positive nucleus surrounded by negative electrons. In order to ionically bond, each group 1 element wants to lose its outer electron to whatever it is going to bond to, eg Cl. ...

Assume 2^(1/3) is rational, so can be written as p/q where p and q are integers with no common factors. p/q = 2^(1/3) (p^3)/(q^3) = 2 p^3 = 2q^3 Hence, p is even. Thus, p can be written as 2r, where r is ...

We know that this is going to be a “U” shaped parabola as the graph is a positive x^2 graph. The y intercept is the point at which x=0. Substituting in 0 gives when x = 0, y = -21.Now we need the x interc...
