Common polygons include triangles, squares, rectangles, parallelograms, trapezoids, pentagons, hexagons, octagons… The perimeter of a polygon is the distance around the outside. In general, to find the perimeter of a polygon, you can add up the lengths of all of its sides.

A compound’s percent composition provides the mass percentage of each element in the compound, and it is often experimentally determined and used to derive the compound’s empirical formula.

(The induced electric field at the points is so large that it removes the charge from the belt.) This can be done because the charge does not remain inside the conducting sphere but moves to its outside surface.

If we divide both sides of the final equation by V T , we get the relationship between the total resistance of the circuit and the individual parallel resistances in the circuit. The total current through the circuit would be the sum of the three currents in the individual resistors.

(b) The charge $q_{2}$ is negative and greater in magnitude than $q_{1}$ , and so the force $F_{2}$ acting on it is attractive and stronger than $F_{1}$ .

The voltage drops occur when the current passes through each of the resistors and the total voltage drop for the entire circuit is equal to the sum of the voltage drops through the three resistors. The current through each of the resistors must be exactly the same because the current in a series circuit is the same everywhere.

(b) If we replace this bulb with a compact fluorescent light that provides the same light output, but at one-quarter the wattage, and which costs $1.50 but lasts 10 times longer (10,000 hours), what will that total cost be?
