What allows to float? Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. When an object floats, it pushes water out of the […]
What causes light beams to be parallel?
What causes light beams to be parallel? A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow […]
What will the era be called when William is King?
What will the era be called when William is King? William certainly has the option of choosing a new regnal name when he becomes King (perhaps one of his middle names: Arthur, Philip, or Louis, or George, like his great-grandfather), but if he keeps William, he would be known as King William V.

Does direction matter measuring momentum?
Does direction matter measuring momentum? Direction does not matter when you are measuring momentum. Momentum can be transferred from one object to another. When objects collide, some momentum is lost. What is the difference between momentum and velocity? As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that […]
What is considered an observation in a data set?

An observation in statistics is a value of something of interest you’re measuring or counting during a study or experiment: a person’s height, a bank account value at a certain point in time, or number of animals. “Observation unit” means the same thing in this context. […]
Is sound a standing wave?
Is sound a standing wave? Standing sound waves open and closed tubes. Sound waves are longitudinal waves in a medium such as air. The loudness or volume of the sound also increases with wave amplitude. In open and closed tubes, sounds waves can exist as standing waves as long as there is at least one […]

Why does sugar melt and not burn?
Why does sugar melt and not burn? Hypothetically, if wood and sugar were assumed to have an identical chemical composition and supplied the exact same amount of heat energy, then any difference in the reaction would need to be derived from the amount of oxygen. A lack of oxygen is why sugar does not readily […]
