When light interacts with matter 3 things can happen? Light can interact with matter in three ways: absorption, transmission, and reflection. 1. ABSORPTION – When a light wave with a identical frequency to an electron’s natural frequency “impinges” upon an atom, the electrons will begin to vibrate as a result (almost like they are “set […]
What is relative term in physics?
What is relative term in physics? A relative term is a term that makes two or more distinct references to objects (which may be the same object, for example in “The Morning Star is the Evening Star”). Is there anything called absolute motion? A body cannot exist at a state of absolute rest or absolute […]
How do I know if my steering rack is part of routine maintenance?
How do I know if my steering rack is part of routine maintenance? Checking the steering box A typical steering-box layout. Check the gasket and seals for leaks, and the moving parts for wear. Measure steering-wheel travel by making a chalk mark on the rim and using your finger as a reference point. Try to […]
Is Moon hotter than Sun?
Is Moon hotter than Sun? Temperatures on the moon are extreme, ranging from boiling hot to freezing cold depending on where the sun is shining. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 […]
What is type solution of brass?
What is type solution of brass? Brass is an alloy made primarily of copper, usually with zinc. Usually you can think of brass as a solid solution consisting of zinc and other metals (solutes) dissolved in copper (solvent). How do you classify brass? According to the hardness, brass includes soft, semi-hard, hard and very hard […]
Which rock is classified as an evaporite?
Which rock is classified as an evaporite? Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates.

Rescue workers and locals search for residents trapped in the debris of a collapsed building in Izmir, Turkey, on October 30, 2020. Why did the […]
What is the Y intercept when given two points?
What is the Y intercept when given two points? Steps Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11) Substitute the slope(m) in the slope-intercept form of the equation. Substitute either point into the equation. You can use either (3,5) or(6,11). Solve for b, which is the y-intercept […]
What are emission spectrums used for?
What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]
Why is a decrease in GDP bad?
Why is a decrease in GDP bad? When GDP goes up, the economy is generally thought to be doing well. Meanwhile, weak growth signals that the economy is doing poorly. If GDP falls from one quarter to the next then growth is negative. This often brings with it falling incomes, lower consumption and job cuts. […]
