What is bubble sort with example? Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order. Example: First Pass: ( 5 1 4 2 8 ) –> ( 1 5 4 2 8 ), Here, algorithm compares the first two elements, and swaps since […]
How can skin drag friction be reduced?
How can skin drag friction be reduced? Friction drag can be reduced by delaying the point at which laminar flow becomes turbulent. This can be accomplished by smoothing the exposed surfaces of the aeroplane by using flush rivets on the leading edges and through painting, cleaning, waxing, polishing or the application of surface coatings. What […]
What are thermodynamic properties?
What are thermodynamic properties? Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system’s state. If the units were changed from per mass to, for example, per mole, the property would remain as it was (i.e., intensive or extensive). What are independent properties in thermodynamics? Two properties are independent if […]
What is the understory layer of the rainforest?
What is the understory layer of the rainforest? The understory is the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor. Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs […]
What happens to the viscosity of a liquid with decrease in temperature?
What happens to the viscosity of a liquid with decrease in temperature? The former effect causes a decrease in the shear stress while the latter causes it to increase. The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag […]
What is Smith chart in transmission lines?
What is Smith chart in transmission lines? The Smith chart is a chart of normalized impedances (or admittances) in the reflection coefficient plane. As such, it allows calculations of all parameters related to transmission lines as well as impedances in open space, circuits, and the like. How does a Smith chart work? The Smith Chart […]
What are knowledge based systems explain with an example?
What are knowledge based systems explain with an example? A knowledge-based system (KBS) is a form of artificial intelligence (AI) that aims to capture the knowledge of human experts to support decision-making. Examples of knowledge-based systems include expert systems, which are so called because of their reliance on human expertise. Which system can be seen […]
What are ways to reduce greenhouse gas emissions?
What are ways to reduce greenhouse gas emissions? The following is a list of steps YOU can take to reduce greenhouse gas emissions: Reduce, Reuse, Recycle. Use Less Heat and Air Conditioning. Replace Your Light Bulbs. Drive Less and Drive Smart. Buy Energy-Efficient Products. Use Less Hot Water. Use the “Off” Switch. Plant a Tree. […]
What do sediment cores tell us?
What do sediment cores tell us? These cores are long cylinders of the earth’s crust, drilled up from beneath the seafloor. When the cores shown here are arranged end-to-end, they show a glimpse of the Earth’s past geology and climate. What discoveries were made by Ocean Drilling? Major Scientific Accomplishments Scientific ocean drilling has advanced […]
What steel are crankshafts made from?
What steel are crankshafts made from? Crankshafts are made from forged steel or cast iron. Crankshafts for high-volume, low-load production vehicles are generally constructed from nodular cast iron, which has high strength (see Appendix D). Fuel-efficient engines require a high power-to-displacement ratio, which has increased the use of forged crankshafts. What is are the manufacturing […]
