What is a line touching a circle called? A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency. What is a line segment in a […]
Can a vehicle run without a thermostat?
Can a vehicle run without a thermostat? You may think your engine would overheat without a thermostat in place, but actually, the opposite is true. A car without a thermostat would never even warm to operating temperature, much less overheat. This will allow your engine to reach optimal operating temperature, improving gas mileage and performance. […]
What is the function of needle valve?
What is the function of needle valve? Needle valves, sometimes referred to as plunger valves, are regulating valves and enable engineers to finely control and regulate water flow and pressure. What is the difference between a globe valve and a needle valve? The difference is precision. Needle valves are similar in design to globe valves. […]
What is the difference between silicon diode and germanium diode?
What is the difference between silicon diode and germanium diode? The primary difference between silicon and germanium diodes is the voltage needed for the diode to turn on (or become “forward-biased”). Silicon diodes require 0.7 volts to become forward-biased, whereas germanium diodes require only 0.3 volts to become forward-biased. What are germanium diodes used for? […]
What is the step by step injection molding process?
What is the step by step injection molding process? These stages are the clamping, injection, cooling and ejection stages. Clamping. Before the mould is injected with material, both halves of the mould have to be closed. Injection. Plastic pellets are fed by means of a hopper into the injection moulding machine. Cooling. Ejection. What is […]
How can the refrigerant temperature in an air cooled condenser be estimated?
How can the refrigerant temperature in an air cooled condenser be estimated? In air-cooled condensers, the temperature difference between the ambient and the condensing temperature is referred to as the condenser split. For example, if the condensing temperature is 110 degrees F and the ambient is 80 degrees, the condenser split would be 30 degrees. […]
Does an air conditioner need to be grounded?
Does an air conditioner need to be grounded? Does the wall sleeve in a built-in air conditioner need to be grounded? Yes, the case is grounded. If the air conditioner is installed properly and is plugged into a properly grounded 3-prong outlet, no special precautions are needed to ground the air conditioner. How do you […]
What is the resistance of a 12v 10w bulb?
What is the relationship between internal and external validity?
What is the relationship between internal and external validity? Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables. External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. […]
