Properly input current above 40 voltage or 100 for example elecrical fan machine is used to perform a task, work output is always more than work
Air pressure decreases with altitude
hope that helps you!
The North Magnetic Pole is the point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, it will point straight down). There is only one location where this occurs, near (but distinct from) the Geographic North Pole and the Geomagnetic North Pole.
