How do you determine if there is a hydraulic jump? A hydraulic jump occurs when the upstream flow is supercritical (F>1). To have a jump, there must be a flow impediment downstream. The downstream impediment could be a weir, a bridge abutment, a dam, or simply channel friction. Water depth increases during a hydraulic jump […]
What color is closest to the central maximum?
What color is closest to the central maximum? Violet and blue will be seen closer to the central maximum — then green and yellow and orange and finally red, farthest from the white central maximum. a) is a diffraction source. Why is diffraction grating better than a prism? However, a diffraction grating is less sensitive […]
What is the similarities between magnetism and gravity?
What is the similarities between magnetism and gravity? Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. Why is gravitational force a non contact force? […]
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 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 […]
Which unit is used to measure the speed of computer?
Which unit is used to measure the speed of computer? Clock speed is measured in units of cycles per second, which is called a Hertz (Hz). Computer boards and CPUs run at rates of millions and billions of Hertz, megahertz (MHz) and gigahertz (GHz). What unit is typically used to measure the speed of a […]
What is the angle of incidence in aviation?
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 […]
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 […]
