What is the meaning of shear stress? Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes. Is shear stress a […]
Can you get saturated air from unsaturated air?
Can you get saturated air from unsaturated air? Certainly. Just lower the temperature of unsaturated air to the point of saturation. That is possible with any air that contains more than zero moisture. At some point the air will be saturated since saturation occurs with less moisture at a lower temperature. How is saturated air […]
What size hydraulic pump do I need for a log splitter?
What size hydraulic pump do I need for a log splitter? If you are serious about making your own backyard log splitter, then you want to have, at a minimum, the following components to provide the right amount of force and power for basic splitting of averaged sized, seasoned logs: A 5 Horsepower engine. A […]
Which gas has highest diffusion rate?
Which gas has highest diffusion rate? Diffusion is inversely proportional to molecular weight. Therefore, NH3 has the highest diffusion rate. Which noble gas diffuses the fastest? Neon Why rate of diffusion is faster in gases? Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their […]
What is filter in circuit theory?
What is filter in circuit theory? A filter is a circuit whose transfer function, that is the ratio of its output to its input, depends upon frequency. There are three broad categories of filter which are widely used: Low-pass filters allow any input at a frequency below a characteristic frequency to pass to its output […]
What is Big O notation with example?
What is Big O notation with example? Big O notation shows the number of operations Big O notation Example algorithm O(log n) Binary search O(n) Simple search O(n * log n) Quicksort O(n2) Selection sort How is Big O notation used to describe the complexity of algorithms? Big O notation is used in Computer Science […]
What caused the Columbia accident?
What caused the Columbia accident? The cause of the accident was a piece of foam that had fallen off the Shuttle’s external fuel tank during launch. The foam struck the left wing of the shuttle, causing serious damage that ultimately led the vehicle to disintegrate when it reentered Earth’s atmosphere. What went wrong in the […]
Which measure of variation is most reliable?
Which measure of variation is most reliable? standard deviation How do you choose the best measure of dispersion? The interquartile range is usually preferable, as it is more informative than the range. Data measured at the interval/ratio level: All three measures of dispersion we have examined are appropriate. The standard deviation is usually preferable. What […]
What is regression equation in statistics?
What is regression equation in statistics? A regression equation is a statistical model that determined the specific relationship between the predictor variable and the outcome variable. A model regression equation allows you to predict the outcome with a relatively small amount of error. What does regression analysis measure? Regression is a statistical method used in […]
