What is the best example of a non positive displacement pump? Centrifugal and propeller pumps are examples of non-positive-displacement pumps. If the output port of a non-positive-displacement pump were blocked off, the pressure would rise, and output would decrease to zero. Although the pumping element would continue moving, flow would stop because of slippage inside […]
What does translation mean in graph?
What does translation mean in graph? Transformations of Graphs Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis. A graph is translated k units horizontally by moving each point on the graph k units horizontally. Definition. What is the transformation process? A transformation process […]
Why do you look left then right then left again?
Why do you look left then right then left again? Intersections are one of the most dangerous areas for any driver. First, as you approach an intersection on a green light, slow down before entering it and make sure to look left-right-left; look left first, look left twice, because the first danger to you is […]
What are the four types of radiation?
What are the four types of radiation? There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle. Why gamma rays has no mass? Gamma rays ( ) are electromagnetic […]
What is the difference between sealed and flooded batteries?
What is the difference between sealed and flooded batteries? A sealed deep cycle battery is also known as a VRLA maintenance-free battery. It is nearly identical to a flooded battery—the only difference is the electrolyte fluid is sealed into the battery. This is why they call it maintenance-free because you don’t have to maintain the […]

Why is Edgenuity so bad?
Why is Edgenuity so bad? Edgenuity sucks because the program fails to engage and teach students, then expects them to do three classes of work for one class. You don’t even need to pay attention to the unskippable 5 minute long videos, just speed through the 25 slides of monotonous teachers that are bad at […]
What happens when an ultrasound wave reaches a boundary?
What happens when an ultrasound wave reaches a boundary? When ultrasound waves reach a boundary between two substances with different densities, they are partly reflected back. The remainder of the ultrasound waves continue to pass through. A detector placed near the source of the ultrasound waves is able to detect the reflected waves. How does […]
