What are 2 examples of mechanical waves? A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. Who discovered scalar waves? Heinrich […]

What does pen stand for?
What does pen stand for? PEN originally stood for “Poets, Essayists, Novelists”, but now stands for “Poets, Playwrights, Editors, Essayists, Novelists”, and includes writers of any form of literature, such as journalists and historians. Why pencils are not used in space? To understand why NASA was so keen on a workable space pen, you have […]
What happens if you get caught climbing the pyramids?
What happens if you get caught climbing the pyramids? According to Ahram Online, an Egyptian newspaper, Egypt’s parliament made it illegal last year for anyone to climb “any antiquity without obtaining a license.” The penalty for doing so can be up to a month in jail and/or a fine ranging from 10,000 to 100,000 Egyptian […]
What three conclusions came from the gold foil experiment?
What three conclusions came from the gold foil experiment? most of the alpha particles did pass straight through the foil. a small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil….Rutherford and the nucleus. What happened Rutherford’s conclusions Most of the alpha particles did pass straight through […]
Why do the two slits need to be small in order for an interference pattern to occur?
Why do the two slits need to be small in order for an interference pattern to occur? The very short wavelengths of visible light explain why interference effects are observed only in special circumstances—the spacing between the sources of the interfering light waves must be very small to separate regions of constructive and destructive interference. […]
How does electrostatic occur?
How does electrostatic occur? Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. The rubbing of certain materials against one another can transfer negative charges, or electrons. […]
Can Methanol hydrogen bond with itself?
Can Methanol hydrogen bond with itself? Methanol is certainly similar to formaldehyde in some ways. It is these strong hydrogen bonds that are responsible for the relatively high boiling point of methanol; there is so much positive charge on the hydrogen of the OH group that it can essentially form a real bond with the […]
Is anyone lost in space?
Is anyone lost in space? A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The two worst disasters both involved NASA’s space shuttle. What are the risks of […]
Why does rain make me feel safe?
Why does rain make me feel safe? Studies have found that when rain sounds enters people’s brain, brain unconsciously relaxes and produces alpha waves, which are very close to the state of brain when human sleeps. Rain sound is generally between 0 and 20 kHz. It is not upsetting. On the contrary, this sound makes […]
