Why Subduction Zone trenches and mountain ranges are formed? Various formations such as mountain ranges, islands, and trenches are caused by subduction and the volcanoes and earthquakes it triggers. Subduction zones are mainly located in the Pacific Ocean. This is because seafloor spreading – the process by which new oceanic crust is created – occurs […]
What is the largest solid conductor listed in the wire tables?
What is the largest solid conductor listed in the wire tables? copper Which of the following conductors when installed in a raceway is permitted to be a solid conductor? Yes, a solid bare copper 10 AWG equipment grounding conductor IS permitted in a metallic raceway. However, a bare aluminum conductor is NOT permitted in a […]
What does it mean to have freedom of expression?
What does it mean to have freedom of expression? Freedom of expression refers to the ability of an individual or group of individuals to express their beliefs, thoughts, ideas, and emotions about different issues free from government censorship.

How is multiple cropping different from mixed farming?
How is multiple cropping different from mixed farming? In mixed cropping or mixed farming, two independent crops are mixed together and grown in an area, whereas the intercropping is a multiple cropping techniques where two or more crops are grown in proximity. … What is multi cropping? In agriculture, multiple cropping or multicropping is the […]
What is being emitted in an LED?
What is being emitted in an LED? LED is an abbreviation of Light Emission Diode, and is a device which emits light by flowing a current to the p-n junction like a semiconductor laser (LD). It emits various wavelength lights in the ultraviolet, visible and infrared regions, corresponding to its band gap energy. Why LED […]
Why are most aircraft painted white?
Why are most aircraft painted white? Painting an aircraft white helps to reflect the sunlight and minimize the amount of energy needed to keep the plane comfortable. Modern planes that are made from composite materials need even more protection from the sun as they can be damaged by UV radiation, which is another reason why […]
Does laminar or turbulent flow have more shear stress?
Does laminar or turbulent flow have more shear stress? Hence, the shear stress is larger in the turbulent flow than that in the laminar flow. Which boundary layer has more energy laminar or turbulent? A turbulent flow boundary layer has more energy than a laminar flow layer, so it can withstand an adverse pressure gradient […]
What type of voltage does a thermocouple produce?
What type of voltage does a thermocouple produce? The voltage output ranges from about -10 to 77 mV (depending on the thermocouple type and measurement temperature). The correlation of temperature versus voltage establishes a relationship that is unique to the various thermocouple types. Does a thermocouple produce AC or DC voltage? Being the thermocouple voltage […]
How do you calculate gear design?
How do you calculate pulley weight?
How do you calculate pulley weight? Calculate the force caused by gravity on the basic pulley system using the following equation: G = M x n (gravitational acceleration). The gravitational acceleration is a constant equal to 9.8 m/s². The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. […]
