The type of circuit depicted above is an example of a parallel circuit. Parallel circuits are circuits that have several pathways for current to flow; the easiest way to see this is by drawing a condensed diagram. If one of the bulbs were removed (that particular pathway was opened so electricity couldn’t flow), the current could simply go through another pathway using another lightbulb and the circuit would still be complete. Series circuits only have one pathway that the current can flow through, which this can’t be since it has multiple. The circuit isn’t shorted since the lightbulb reduces the voltage to zero, and the circuit is closed since the lightbulbs are on.

<em>K</em> = 2.4 × 10^(-72)
<em>Step 1</em>. Determine the <em>value of n
</em>
Zn^(2+) + 2e^(-) → Zn
2Cl^(-) → Cl_2 + 2e^(-)
Zn^(2+) + 2Cl^(-) → Zn + Cl_2
∴ <em>n</em> = 2
<em>Step 2</em>. Calculate <em>K</em>
log<em>K</em> = <em>nE</em>°/0.0592 V = [2 × (-2.12 V)]/0.0592 V = -71.62
<em>K</em> = 10^(-71.62) = 2.4 × 10^(-72)
Answer & Explanation:
In physics, a contact force is a force that acts at the point of contact between two objects, in contrast to body forces. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics. Contact force is the force in which an object comes in contact with another object. Contact forces are also direct forces. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball or pushing a desk across a room are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse.
