The cost of running an air conditioner per hour depends on the size, efficiency, and the electricity rate in your area. Generally speaking, an average air conditioner can cost anywhere from 10 to 20 cents per hour.

A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. As the crankshaft rotates, the connecting rod causes the piston to move up and down within the cylinder. On the upward stroke, the piston draws a fresh air-fuel mixture into the cylinder through an intake port located in the cylinder wall. When the piston is near the top of its stroke, the spark plug ignites the mixture, causing combustion. As the piston moves downward from top dead center, it compresses the air-fuel mixture. Combustion forces the piston back up, creating the power stroke. As the piston travels back down, the exhaust port opens, allowing the burned gases to escape the cylinder. This completes the combustion cycle and the process begins again.

If the audio of your video file is not working, you can use audio repair software such as Adobe Audition to repair the sound. Once the audio is repaired, you can then re-encode it into the video file and your video should have sound. You can also try converting the file to a different format to see if the sound will work on that format.
