How long did 17th century plague last?
How long did 17th century plague last? Between 1563 and 1665, London experienced four plagues that each killed one fifth of the city’s inhabitants. This column uses 790,000 burial records to track the plagues that recurred across London (epidemics typically endured for six months). How long did Spanish flu last? The influenza pandemic of 1918–19, […]
What type of energy is wasted?
What type of energy is wasted? Heat energy is the most easily dissipated form of energy. Light energy is frequently energy seen in combustion, and is a type of wave motion. Sound energy is another type of wave motion caused by the vibration of molecules in the air. Like heat energy, sound is a type […]

What is the Trypanophobia?
What is the Trypanophobia? Trypanophobia is defined as extreme fear of medical procedures involving injections or needles. What is Ommetaphobia? Ommetaphobia describes an extreme fear of eyes. Like other phobias, this type of fear can be strong enough to interfere with your daily routine and social activities, while also being considered irrational because of the […]
What do coefficients represent in a chemical equation?
What do coefficients represent in a chemical equation? Coefficients are used in all chemical equations to show the relative amounts of each substance present. This amount can represent either the relative number of molecules, or the relative number of moles (described below). If no coefficient is shown, a one (1) is assumed. How do you […]
Is net force always 0?
Is net force always 0? When an object moves with constant velocity, the total net force on the object is always zero. If you have applied force, there’s another force (or, many forces) like friction to counterbalance it. Is normal force equal to mg? Normal force is equal to mg only when the object is […]
How many earthquakes does Alaska have?
How many earthquakes does Alaska have? Alaska has 11% of the world’s earthquakes, and 3 of the six largest in recorded history were located there. Since 1900, Alaska has had one magnitude 7 or 8 earthquakes per year, 45 earthquakes of magnitude 6 or 7, and 10,000 quakes overall annually. Why does Alaska get so […]
