What was the early theory of continental drift? Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents. What German scientist […]
What is the mean of the sampling distribution of X Bar?
What is the mean of the sampling distribution of X Bar? The Sampling Distribution of the Sample Mean. If repeated random samples of a given size n are taken from a population of values for a quantitative variable, where the population mean is μ (mu) and the population standard deviation is σ (sigma) then the […]
What is the safety measurement system?
What is the safety measurement system? The Safety Measurement System (SMS), a branch of the Federal Motor Carrier Safety Administration (FMCSA), identifies and intervenes with drivers who have demonstrated unsafe driving behavior. It uses seven distinct categories, known as BASICs, to identify, categorize, and rank drivers to prioritize for intervention. Who is affected by the […]
What is the difference between single crystal and polycrystal?
What is the difference between single crystal and polycrystal? Single crystals have infinite periodicity, polycrystals have local periodicity, and amorphous solids (and liquids) have no long-range order. A polycrystalline solid or polycrystal is comprised of many individual grains or crystallites. Why are polycrystalline materials stronger than single crystals? Since plastic deformation of a single grain […]

What are the functions of foundation?
What are the functions of foundation? Following are the main functions of foundations : To transmit and distribute the total load of the structure to a larger area of underlying support. To prevent differential settlement of the structure. To provide stability to the structure. What are machine foundations? Machine foundations are special types of foundations […]
Why Subduction Zone trenches and mountain ranges are formed?
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 […]

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 is the amount of force that a braking system requires the driver to apply to stop a vehicle?
What is the amount of force that a braking system requires the driver to apply to stop a vehicle? On a hydraulic brake system, the driver generates force by pressing on the brake pedal. The force is then amplified by the pedal, booster and master cylinder. The driver will modulate the pressure on the pedal […]
