How do cell phones affect communication? If you put a cell phone into a social interaction, it does two things: First, it decreases the quality of what you talk about, because you talk about things where you wouldn’t mind being interrupted, which makes sense, and, secondly, it decreases the empathic connection that people feel toward […]
Can a sailboat sail directly into the wind?
Can a sailboat sail directly into the wind? A sailboat cannot make headway by sailing directly into the wind (see “Discussion,” below); the point of sail into the wind is called “close hauled”. Sailing into the wind is possible when the sail is angled in a slightly more forward direction than the sail force. What […]
What is the error in trapezoidal rule?
What is the error in trapezoidal rule? It follows that if the integrand is concave up (and thus has a positive second derivative), then the error is negative and the trapezoidal rule overestimates the true value. What is the order of error in trapezoidal rule? We know that trapezoidal method should not be give any […]

What are the 5 lean principles?
What are the 5 lean principles? According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection. What are the 4 principles of lean? Let us get the trend straight by understanding 4 Lean principles, which needs to be considered by every Lean practitioner the moment he talks […]
What are the differences physically and logically between the two printing configurations network attached printing and network attached printer sharing?
What are the differences physically and logically between the two printing configurations network attached printing and network attached printer sharing? What are the differences, physically and logically, between the two printing configurations: Network-attached Printing and Network-attached Printer Sharing? They are essentially the same physically. Logically, the print jobs are handled differently. Your environment includes many […]
What is a moment arm biomechanics?
What is a moment arm biomechanics? The moment arm (lever arm) of a force system is the perpendicular distance from an axis to the line of action of a force. In other words, moment arm determines the quality of the torque. An important concept to remember is that the moment arm changes with the angle […]
Why is the 2nd Law of Thermodynamics?
Why is the 2nd Law of Thermodynamics? The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered […]
What are the methods of dimensional analysis?
What are the methods of dimensional analysis? Dimensional analysis is a mathematical technique used to predict physical parameters that influence the flow in fluid mechanics, heat transfer in thermodynamics, and so forth. The analysis involves the fundamental units of dimensions MLT: mass, length, and time. What are the three uses of dimensional analysis? We make […]
