What if time was absolute? Unlike relative time, Newton believed absolute time was imperceptible and could only be understood mathematically. Thus, every object has an absolute state of motion relative to absolute space, so that an object must be either in a state of absolute rest, or moving at some absolute speed. What is an […]
What decreases as elevation increases?
What decreases as elevation increases? As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. How much does temperature change with elevation? Near the Earth’s surface, air gets cooler the higher you climb. As […]
How do you find the intensity of unpolarized light?
How do you find the intensity of unpolarized light? When unpolarized light is polarized with two polarizers, the intensity becomes I=I0cos2(θ) (Malus’s law). How do you measure light intensity? The intensity of light is inversely proportional to the square of the distance. This means that as the distance from a light source increases, the intensity […]

What kind of energy is possessed by water stored in a dam?
What kind of energy is possessed by water stored in a dam? The water high up in the dam contains gravitational potential energy. This is transferred or changed its form into kinetic energy as the water rushes down through tubes inside the dam. The moving water will rotate electrical generators, which are being built inside […]
What can Prism do?
What can Prism do? Prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum. What can be used to split white light? White light can be split […]
What are biogeochemical cycles and why are they important?
What are biogeochemical cycles and why are they important? Biogeochemical cycles help explain how the planet conserves matter and uses energy. The cycles move elements through ecosystems, so the transformation of things can happen. They are also important because they store elements and recycle them. What is the purpose of biogeochemical cycles? However, the biogeochemical […]
