Why light shines off of a mirror? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. This allows us to see […]
What are three types of models?
What are three types of models? Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models. What is simple model? A Simple Model exists to make the skill set required to build financial models more accessible. The intention is to create simple material and facilitate the learning […]
What is the very first step in the proton-proton cycle?
What is the very first step in the proton-proton cycle? The first step in this process is the collision of two protons where proximity permits the strong nuclear force to bind them together. The resulting combination is not stable, and one of the protons will decay to become a neutron, and this forms a stable […]
Is it safe to swim to a sandbar?
How do you determine instantaneous speed?
How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]
Which is best analog or digital?
Which is best analog or digital? Digital recordings can have a greater signal-to-noise ratio depending on the bit depth of the recording. This jump in elevation can create a digital noise. The smooth analog signal matches the recorded sound wave better than the steps of a digital recording. What are the three components of a […]
How can you speed up an exothermic reaction?
How can you speed up an exothermic reaction? Decrease the temperature in Exothermic reactions (Reactions that release energy, or become hot) Add a catalyst (A substance that reduces activation energy, speeding up the reaction) Increase the concentration of reactants. Increase the concentration of catalysts. Why is a match exothermic? – when Energy is released along […]
Is a woodchuck and a beaver the same thing?
Is a woodchuck and a beaver the same thing? The woodchuck and the beaver belong to the same rodent species, and are closely related to the squirrel family. Though they exhibit certain resemblance like the ever-growing teeth, gnawing habits, and ability to regulate temperature, there are a lot of differences in their habitats, breeding and […]
What is the pressure at the bottom of a swimming pool that is 3 meters in depth?
What are the five changes of state?
What are the five changes of state? Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. What are the 22 states of matter? What are the 22 states of matter? Solid. Liquid. Gas. Plasma. Bose-Einstein Condensate. Excitonium. Degenerate Matter. Photonic Matter. What are the 7 types of matter? The seven states of […]
