Unlike Direct Variation, in which the result is given just by one variable and a constant of variation, in Joint Variation, there are two variables Formula If the result is given by two different variables and , multiplied by a constant ,…

Average Velocity is calculated using the change in displacement over a period of time. The change in displacement is calculated as the initial displacement subtracted from the final displacement, that quantity divided by the initial time subtracted from the final time.

Derivation of the Friedmann Equations[1] from the Newtonian First Derivative of the Scale Factor a is the scale factor, not acceleration. Notice it is not expressed as a vector. The scale factor is scalar; It has no direction, only magnitude. It describes the instantaneous…
