Advent Wreath Candles. Set on the branches of the wreath are four candles: three purple candles and one pink candle. In the center of the wreath sits a white candle. As a whole, these candles represent the coming of the light of Christ into the world. On the first Sunday of Advent, the first purple candle is lit.
In mathematics,  a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
May 1, 2014. Friction is due to the weight of the object and the coefficient of friction. The coefficient is a number that tells you how much friction you would expect between pairs of surfaces. Force friction= weight x coefficient of friction. So as the weight increases so does the amount of friction. Note on coefficients of friction: Sand paper may have a coefficient of 0.78 (the closer to 1, the more friction you will have), and a piece of ice sliding across a sheet of ice may have a coefficient of 0.02, meaning almost no friction.
