If it’s a multiple choice question A is the correct answer
4mx2mx3m
Explanation:
[H+]=10^-pH
[H+]=10^-9.2
[H+]=6.031x10^-10
[OH-]=1x10^-14÷[H+]
[OH-]=1x10^-14÷[6.031x10^-10]
[OH-]= 1.66x10^-5
im pretty sure this is right

Answer: When you turn a light on it becomes bright :)
In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.
