What is the relation between refractive index and intensity? The intensity of light (as calculated from time average of the poynting vector) is given by I=(1/2)ϵvE20. Here the intensity is dependent on the velocity of light in the medium. The refractive index also depends on the velocity of light. What is the speed and intensity […]
What factors affect collision theory?
What factors affect collision theory? Key Takeaways Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate. What are the 5 major factors […]
Can we land on an asteroid?
Can we land on an asteroid? Landing. Asteroids are not large enough to produce significant gravity, making it difficult to land a spacecraft. This technology allowed for the orientation control and orbit control of the spacecraft that guided it to land on Ryugu. How could we redirect an asteroid? Under consideration for deflecting an asteroid […]
Is gold used in semiconductors?
Is gold used in semiconductors? A good conductor of heat and electricity, it is also the most malleable and ductile of all metals. Gold is used in many aspects of semiconductor manufacturing, particularly in the assembly or packaging processes. Its most widespread use is in wirebonding. Why is gold used in motherboards? Principally used in […]

At what temperature does all motion cease theoretically?
At what temperature does all motion cease theoretically? A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius. Which temperature does all molecular motion steps? Step by […]
How much food is being wasted per year or every 10 years?
How much food is being wasted per year or every 10 years? An estimated 1.3 billion tonnes of food is wasted globally each year, one third of all food produced for human consumption. In ten years, the United States will waste the equivalent of 66 tons of food per second across the globe. What country […]
Does Heat travel up or down?
Does Heat travel up or down? “Heat” does not travel up. Heat can travel in all directions. The direction heat travels depends on the specifics of a system not in thermal equilibrium. In contrast, “hot air” on earth’s surface tends to go up. What material reflects the most heat? Note that a metal will only […]
What makes science unique from other endeavors?
What makes science unique from other endeavors? What makes science unique from other endeavors? Science sets up a theoretical model of what is happening, which can be reproduced by everyone. You just studied 22 terms! What is the human person flourishing in terms of science and technology? Human flourishing involves the rational use of […]
