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 […]
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 […]

Italy, Spain and other countries joined it until November 1941. Which countries were pro Axis in ww2? The three principal partners in the Axis alliance were Germany, Italy, and Japan. These three […]
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? […]
What location has the highest air pressure?
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 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 […]
What is spectrophotometer and its uses?
What is spectrophotometer and its uses? A spectrophotometer is an analytical instrument used to quantitatively measure the transmission or reflection of visible light, UV light or infrared light. Applications for specs include measurement of substance concentration such as protein, DNA or RNA, growth of bacterial cells, and enzymatic reactions. What is spectroscopy principle? What Is […]
How do you determine if there is a hydraulic jump?
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 is oxygenated blood called?
What is oxygenated blood called? Oxygenated blood is also called arterial blood as the arteries deliver oxygenated blood to different parts of the body through the pulmonary veins. Where does oxygenated blood come from? Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where […]
