What is the angle of incidence in aviation? On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle or setting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum […]
What weighs approximately 1 Newton?
What weighs approximately 1 Newton? In general terms anything that has a mass of 102 grams is said to have a weight of one Newton, because a 0.102 kg object accelerating at 9.81 m/s2 gives you a force of one Newton. Local grocery stores have many things that weigh one Newton. In the fruit department, […]
Will a diode reduce voltage?
Will a diode reduce voltage? Diodes allow electricity to flow in only one direction, but a diode will only conduct electricity, when the supply reaches its threshold. The threshold for common silicon diodes is 0.6 volts. After each diode, the voltage can be seen to drop by 0.6 volts. In this way, diodes can be […]
What location has the highest air pressure?

World: Highest Sea Level Air Pressure Below 750 meters At 1200GMT on 31/12/1968, the pressure at the center of huge anticyclone over Siberia reached 1083.8 hPa and was authenticated. Which city has highest air pressure? A frigid air mass in Mongolia may have just crushed a world record […]
What two forces limit the height of capillary action will take water up a tube?
What two forces limit the height of capillary action will take water up a tube? Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface […]
What is a good amount of kJ to burn a day?
What is a good amount of kJ to burn a day? In order to achieve weight loss an individual needs to consume less energy (kilojoules) than the will body burn. For example if an individual needs 8,700 kilojoules per day to maintain weight, reducing daily intake to 6,600 kilojoules (assuming exercise stays the same), should […]
What is the effect of molecular weight on melting and boiling points of alkanes?
What is the effect of molecular weight on melting and boiling points of alkanes? Their melting and boiling points of alkanes are relatively low. The higher the molecular weight (the greater the number of carbons), the higher the boiling point. What is the major use of alkanes? Use of Alkanes Alkanes are important raw materials […]

How long was John Adams away from his wife? Abigail and John Adams would endure long periods of separation for the first fifteen years of their marriage. What made John Adams a good president? Learned and thoughtful, John Adams was more remarkable as a political philosopher than as a politician. When Adams became President, the […]
What is temperature on a PV diagram?
What is temperature on a PV diagram? With everything tied together by the ideal gas law, one variable can always be described as dependent on the other two. Temperature is the slave of pressure and volume on a pressure-volume graph (PV graph). What is name of the curve obtained in PV diagram? Only two thermodynamic […]
Is compulsion the same as addiction?
Is compulsion the same as addiction? The difference between compulsive behaviors and addiction is urge versus need. A compulsion is an insatiable urge to do something. Addiction is a need to do something to experience pleasure or remove discomfort. Is addiction a form of OCD? OCD causes anxiety, depression and even suicidal thoughts when left […]
