How do you calculate a mix ratio? Divide 1 by the total number of parts (water + solution). For example, if your mix ratio is 8:1 or 8 parts water to 1 part solution, there are (8 + 1) or 9 parts. The mixing percentage is 11.1% (1 divided by 9). How do you calculate […]

What can cause a compass to malfunction? In navigation manuals, magnetic deviation refers specifically to compass error caused by magnetized iron within a ship or aircraft. This iron has a mixture of permanent magnetization and an induced (temporary) magnetization that is induced by the Earth’s magnetic field. What does a compass react to? A compass […]

Why tidal energy is bad? Intermittent: Tidal energy can only be produce electricity during tidal surges, limiting electricity generation to 10 hours per day. Expensive: Technology for generating electricity from tidal energy is relatively new and not yet commercially profitable. Tidal power plants are also expensive to build and maintain. Why is tidal power not […]
