What is called electric resistance? In electronics and electromagnetism, the electrical resistance of an object is a measure of its opposition to the flow of electric current. The reciprocal quantity is electrical conductance, and is the ease with which an electric current passes. Does 240V need a neutral? A 240V load needs two “ungrounded conductors”, […]

Where was the node in the Tacoma Narrows Bridge collapse?
Where was the node in the Tacoma Narrows Bridge collapse? In the case of Tacoma Narrows, there was a node (no twisting) exactly at the middle of the center span. How long did the Tacoma Narrows Bridge last? After 29 months of construction, a new and much safer Tacoma Narrows Bridge opened on Oct. 14, […]
What does fully ionized mean?
What does fully ionized mean? When referred to an atom, “fully ionized” means that there are no bound electrons left, resulting in a bare nucleus. Regular stars largely contain hydrogen and helium that are fully ionized into protons (H+) and alpha-particles (He2+). Which element would have the highest ionization energy? helium What is Fluorines ionization […]

Did Maria Belon lose her leg in the tsunami?
Did Maria Belon lose her leg in the tsunami? She lost part of a leg in the tragedy, but miraculously (spoiler alert), she managed to reunite with the rest of her family by sheer luck. More than 283,000 died. Belon, once a family doctor turned stay-at-home mom, emerged from the ordeal a different person. How […]

How does a photon interacts with matter?
How does a photon interacts with matter? In a pair-production interaction, the photon interacts with the nucleus in such a manner that its energy is converted into matter. The interaction produces a pair of particles, an electron and a positively charged positron. These two particles have the same mass, each equivalent to a rest mass […]
Why is energy released in a fission reaction?
Why is energy released in a fission reaction? Fission is the splitting of heavy nuclei (such as uranium) – in two smaller nuclei. This process needs less energy to ‘bind’ them together – so energy is released. The larger nuclei again needs less energy to hold it together – so energy is released. What is […]
What are examples of reactants?
What are examples of reactants? Examples of Reactants The wax of a candle and oxygen in air are reactants in a combustion reaction. When you burn methane gas, the reactants are methane (CH4) and oxygen in air (O2). When water forms from its elements, the reactants are hydrogen (H2) and oxygen (O2) gas. What are […]
