What is condition for no refraction? If the refractive indices are same in both medias then there will be no refraction and light will pass without any refraction. And when the incident ray is striking perpendicular to one media to another the light will pass without any refraction. What are the two requirements for refraction? […]
Where does the process of subduction occur?
Where does the process of subduction occur? Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones. What happens at a […]
How do you express the life of bearing?
How do you express the life of bearing? Bearing life is usually expressed as the number of hours an individual bearing will operate before the first evidence of metal fatigue develops. The usual life rating for industrial applications is called “L-10” life. Simply put the L-10 life is the number of hours in service that […]
What is reverse inversion?
What is reverse inversion? Inversion is the practice of thinking through problems in reverse. It’s asking how an endeavor could fail, and then being careful to avoid those pitfalls. This idea comes originally from algebra, where an equation is oftentimes easier to solve if you invert it. But it also works for non-math problems. What […]
What are the three basic parts of an electric generator?
What are the three basic parts of an electric generator? The main components of an electric generator can be broadly classified as follows: Engine. Alternator. Fuel System. Voltage Regulator. Cooling and Exhaust Systems. Lubrication System. Battery Charger. Control Panel. What parts are found in an electric generator? Generators convert a fuel source into usable energy […]
Is displacement the area under a velocity time graph?
Is displacement the area under a velocity time graph? The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards. The displacement can also be negative. An area beneath the x-axis has a negative value. What is a displacement vs time graph? Displacement-time graphs show how the […]
What is the difference between a cast fossil and a mold fossil?
What is the difference between a cast fossil and a mold fossil? Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains. This is called […]
What prompts an engineer to improve world?
What prompts an engineer to improve world? But what prompts an engineer to improve our world? Well, they solve problems. Problems are an engineer’s inspiration, and maths and science are the creative tools they use to solve them. A mechanical engineer designed the engine, a mechatronics engineer devised that controls. How have engineers changed the […]
Is a kilo 1000?
Is a kilo 1000? Kilo is a decimal unit prefix in the metric system denoting multiplication by one thousand (103). It is used in the International System of Units, where it has the symbol k, in lower case. The prefix kilo is derived from the Greek word χίλιοι (chilioi), meaning “thousand”. What does kilo mean […]
How do you know if someone is dissociating?
How do you know if someone is dissociating? Some common signs and symptoms of being in a dissociate state can be: spacing out. glazed, blank look/ staring. mind going blank. mind wandering. a sense of the world not being real. watching yourself from seemingly outside of your body. detachment from self or identity. out of […]
