What are the 3 schools of psychology? The following are some of the major schools of thought that have influenced our knowledge and understanding of psychology: Structuralism and Functionalism: Early Schools of Thought. Gestalt Psychology. The Behaviorist School of Thought in Psychology. The Psychoanalytic School of Thought. The Humanistic School of Thought. What are the […]

How do you find acceleration without time? If the acceleration is constant, it is possible to find acceleration without time if we have the initial and final velocity of the object as well as the amount of displacement. The formula v2=u2+2as where v is the final velocity, u is the initial velocity, a is the […]

Which layer is closest to space? Layers of Earth’s Atmosphere exosphere—contains few particles that move into and from space. exobase—the lower boundary of the exosphere. thermosphere—temperature increases with height. The International Space Station orbits Earth in this layer. mesopause—the boundary between the mesosphere and the thermosphere; the coldest place on Earth. What layer are satellites? […]

Are globular clusters in the Milky Way? Globular star clusters are known to be located mostly in the great spherical halo of the Milky Way. Spiral galaxies like our Milky Way contain stars, gas and dust, mostly organized into a flat disk containing the spiral arms, but with the addition of a more rounded bulge […]

What is the formula to find the mass? Determine mass with force and acceleration. Newton’s second law of motion states that force equals mass times acceleration: F = ma. If you know the net force on the object, and it’s acceleration, you can rearrange this formula to find the mass: m = F / a. […]

Is water displacement dependent on mass? The concept of Archimedes’ principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = […]

Why is o not stable? One oxygen atom is unstable since it has only 6 electrons in the outermost shell. For an atom to be stable it needs 8 electrons. So, for the oxygen atom to be stable it requires two more electrons in the valence shell. Why does O2 exist but not S2? In […]

How do astronomers identify stars? Thus, astronomers can identify what kinds of stuff are in stars from the lines they find in the star’s spectrum. This type of study is called spectroscopy. The science of spectroscopy is quite sophisticated. Why do stars wobble? We all know that the chains of gravity shackle a planet to […]

Is it better to wear a hat in the sun? Wearing a hat outdoors is also great way to protect your hair, eyes, and skin from the sun’s ultraviolet (UV) rays. While you still need to slather your skin with sunscreen that protects against both UVA and UVB rays, a hat can help give added […]

What are the 8 lab safety rules? General Laboratory Safety Rules Know locations of laboratory safety showers, eyewashstations, and fire extinguishers. Know emergency exit routes. Avoid skin and eye contact with all chemicals. Minimize all chemical exposures. No horseplay will be tolerated. Assume that all chemicals of unknown toxicity are highly toxic. What are the […]
