What is an example of state-dependent memory? State-dependent memory refers to improved recall of specific episodes or information when cues relating to emotional and physical state are the same during encoding and retrieval. For example, a person may be alert, tired, happy, sad, drunk or sober when the information was encoded. … What are the […]

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 […]

How can you reduce unwanted energy transfers in a machine with moving touching components? Mechanical devices can be made more efficient through lubrication to reduce the friction between moving parts of a machine and increase the amount of useful energy transferred. Can you put too much insulation in your attic? It is possible to over-insulate […]

Why do roller coasters feel faster than cars? ELI5: why does going 60mph on a roller coaster feel so different than going 60mph in a car? Because 1) they’re open so you feel the wind and 2) they don’t go in long, straight lines. They go all over and throw you left, right, up, and […]

Who is the father of cosmology? ACHARYA KAPIL How do Cosmologists study the universe? There are two main ways in which cosmological observations support perturbed FLRW models. First, cosmologists use matter and radiation in the universe to probe the background spacetime geometry and its evolution. What is Africa cosmology? In the framework of African cosmology, […]

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 […]

What are 2 similarities and 2 differences between ionic and covalent bonds? The molecules that are formed from the ionic and covalent bonds are neutral. This is because, in an ionic bond, two opposite charges cancel each other while in a covalent bond, neutral components shared the pair of electrons. Ionic and covalent, both are […]

Do projectiles have a predictable path? Projectiles do not follow a predictable path. Where will the ball have the smallest speed? The speed is smallest at the highest point of its flight path because the y- component of the velocity is zero. At what point of the projectile path the speed is i minimum and […]

What is called stereopsis? Stereopsis (from the Greek στερεο- stereo- meaning “solid”, and ὄψις opsis, “appearance, sight”) is a term that is most often used to refer to the perception of depth and 3-dimensional structure obtained on the basis of visual information deriving from two eyes by individuals with normally developed binocular vision.
