Is humidity hot or cold? Humidity is the presence of water molecules in the air. High humidity levels are more likely in warm air, because it can hold more water at higher temperatures. If the air in your home is warm, it will also have the capacity to hold a lot of moisture. What is […]

What happens if an atom is not electrically neutral? Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons. Materials with an excess of electrons are negatively charged. Those with a deficiency of electrons are positively charged. What if there is no electron? You would become plasma as […]

Is Mega 10 6? Mega is a unit prefix in metric systems of units denoting a factor of one million (106 or 1000000). It has the unit symbol M. It was confirmed for use in the International System of Units (SI) in 1960. What is this number 1000000000000000000000000? Some Very Big, and Very Small Numbers […]

How do you calculate watts? AC three phase amps to watts calculation formula P(W) = √3 × PF × I(A) × VL-L(V) So watts are equal to square root of 3 times power factor PF times amps times volts: watt = √3 × PF × amp × volt. or. W = √3 × PF × […]

What is the most germicidal wavelength of UV light? 260 to 265 nm What happens if thymine dimers are not repaired? The more you expose your skin to UV light, the more likely you are to get the very unlucky combination of thymine dimers in a cell that are not repaired and lead to cancer […]
