What is the relationship between height and pressure? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a […]
How do you calculate precision?
How do you calculate precision? Precision is a metric that quantifies the number of correct positive predictions made. Precision, therefore, calculates the accuracy for the minority class. It is calculated as the ratio of correctly predicted positive examples divided by the total number of positive examples that were predicted. How do you find percent accuracy? […]
What are the examples of divergent boundaries?
What are the examples of divergent boundaries? Examples Mid-Atlantic Ridge. Red Sea Rift. Baikal Rift Zone. East African Rift. East Pacific Rise. Gakkel Ridge. Galapagos Rise. Explorer Ridge. What are the example of divergent boundary? An example of a divergent boundary is the mid Atlantic Ridge (there are mid ocean ridges in the Indian, and […]
What is a travel time?
What is a travel time? : a usually specified period of time spent in traveling at work or from the entrance of a business establishment to the place where work is actually done (as in portal-to-portal travel or deadheading) for which compensation may be demanded or paid. Is travel time working time? Travel time to […]
Can two independent variables be correlated?
Can two independent variables be correlated? H. M. BLALOCK, JR. Whenever two supposedly independent variables are highly correlated, it will be difficult to assess their relative importance in determining some dependent variable. The higher the correlation between independent variables the greater the sampling error of the partials. Can an experiment have no independent variable? In […]
Why do crocodiles eat humans?
Why do crocodiles eat humans? Crocodiles do not necessarily set out to hunt humans. They are clearly ferocious hunters, but they are opportunistic predators. Any animal that moves is fair game. They will even venture onto land to find prey. Why do crocodiles cry fake tears? Crocodile tears (or superficial sympathy) is a false, insincere […]
What is the role of gravity in the formation of the solar system?
What is the role of gravity in the formation of the solar system? Gravity is the powerful force that glues our universe together. Gravity helped form our solar system, the planets, and the stars. It holds the planets in orbit around the Sun, and moons in orbit around the planets. The gravitational pull of the […]
How many Earth years is a Lightyear?
Why is derating necessary?
Why is derating necessary? Derating increases the margin of safety between part design limits and applied stresses, thereby providing extra protection for the part. By applying derating in an electrical or electronic component, its degradation rate is reduced. The reliability and life expectancy are improved. How do you calculate derating current? Selection of cable – […]
