What is the purpose of having an electromagnet in an electric bell? When an electric current flows through the coils, the electromagnet creates a magnetic field which pulls the armature towards it, causing the hammer to strike the bell. What makes an electromagnet stronger? The strength of an electromagnet can be increased by increasing the […]
How do you keep a car battery from dying when not in use?
What is aileron droop?
What is aileron droop? The purpose of aileron droop is to use the ailerons as wing flaps. Wing flaps increase the lift generated by the wings at low speed. By deflecting both the ailerons downwards, they change the wing camber and act like simple plain flaps. They can still act as ailerons, by normal differential […]
What factors cause unethical behavior?
What factors cause unethical behavior? Results show that exposure to in-group members who misbehave or to others who benefit from unethical actions, greed, egocentrism, self-justification, exposure to incremental dishonesty, loss aversion, challenging performance goals, or time pressure increase unethical behavior. What are common pressures for an unethical leader? 1. You are making it psychologically unsafe […]
Why the actual thermal efficiency is always less than the Carnot efficiency?
Why the actual thermal efficiency is always less than the Carnot efficiency? So if all the heat input was converted to useful work, the engine would have an efficiency of one (100% efficient). Thus, the efficiency is always less than one. Carnot showed that the maximum efficiency of a heat engine depends only on the […]
What is the process for scheduling a project?
What is the process for scheduling a project? Project scheduling involves creating a document, these days usually a digital document, that details the project timeline and the organizational resources required to complete each task. The project schedule must be accessible to every team member. What is meant by scheduling in project management? Scheduling in project […]
What happens to the viscosity of liquid with the increase in temperature?
What happens to the viscosity of liquid with the increase in temperature? With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. Does viscosity of most […]
Which of the following network cabling types provides the best resistance to EMI?
Which of the following network cabling types provides the best resistance to EMI? Because of this shield, coax is highly resistant to electromagnetic interference (EMI). Twinaxial cable has solid copper wires which lower transceiver latency. Twisted pair cable has two or more pairs of copper wires which are twisted and reduces attenuation and crosstalk. Which […]
Is Clinical Psychology a STEM field?
Is Clinical Psychology a STEM field? Psychology is the science of behavior and its underlying processes. Therefore, given the definition and goals of STEM initiatives, psychology should consistently qualify as a STEM discipline. Is Veterinary Medicine a STEM field? Yes, veterinary medicine is considered a STEM career. What Strand is best for psychology? Students who […]
What are condition monitoring techniques?
What are condition monitoring techniques? Condition monitoring to help prevent machine failure Condition monitoring is the process of monitoring machinery – by vibration, temperature or other methods – to identify a significant change which could indicate a developing fault. It is a major component of predictive maintenance. What are the various methods and devices for […]
