Which type of reaction releases energy quizlet? Chemical reactions that release energy, usually in the form of heat, are called exothermic reactions. Chemical reactions that absorb energy, usually in the form of heat, are called endothermic reactions. Many types of reactions can be endothermic or exothermic. How is energy released in a chemical reaction quizlet? […]

Can you boil water with a tealight candle? This calculation suggests that a tea light should be able to boil 4 or 5 pots of water. However, not all the energy will go nto the hot water and you will have to heat up the pot as well as the water. So I would guess […]

Why uniform circular motion is not SHM? Circular motion is not a form of simple harmonic motion. SHM occurs when a particle is subjected to a force that is anti-parallel to the particle’s motion. Thus, they are very different in nature. What is epoch in SHM? An epoch, in physics, refers to the displacement acquired […]

Why are my chickens pooping in their nesting boxes? Chickens generally will only poop in the nesting boxes if they are sleeping in them at night. Often young pullets will try to sleep in the boxes instead of on the roosts with the older hens. To prevent this, take any little ones out of the […]

Who helped Tesla? Elon Musk How did the Tesla coil impact society? Circuitry using the Tesla coil was part of the first generation of transmitters to carry wireless telegraphy. Tesla used his brainchild to research such diverse areas as lighting, X-rays and electric power transmission. Customized Tesla coils are now frequently used to ignite powerful […]

What did Pythagoras believe about the earth? An astronomical system positing that the Earth, Moon, Sun and planets revolve around an unseen “Central Fire” was developed in the 5th century BC and has been attributed to the Pythagorean philosopher Philolaus. Did Pythagoras go crazy? One of Pythagoras’ strangest obsessions with food was his relationship to […]

Can you touch your eardrum? And if you press on those, it sends shock waves into the inner ear, and the inner ear is responsible for hearing and balance. So if you tap on the eardrum, you’re sending shock waves into the inner ear and you can cause problems with your hearing and balance. Is […]

Why does losing gaining an electron cause the other element to gain lose atoms? Answer: A positive ion is formed where an atom has more protons than electrons. Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to […]

Does oxygen form a positive or negative ion? Negative ions are called anions . Oxygen is in group 6. An oxygen atom has six electrons in its outer shell. The atom is more stable if it has a full outer shell….Forming negative ions. Atom name Ion name Sulfur Sulfide Which form of oxygen is the […]

Is acceleration and velocity the same? Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per […]
