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 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 […]

What do caribou get eaten by? Foxes, ravens, owls,haegars and hawks are other carrion eaters or scavengers that feed on caribou kills. Native peoples have relied […]
Why can self-heating cans be used only once?
Why can self-heating cans be used only once? Answer: Self-heating food packaging is active packaging with the ability to heat food contents without external heat sources or power. Packets typically use an exothermic chemical reaction. Why self-heating cans are very expensive? Self-heating cans have dual chambers, one surrounding the other, making a self-heating food package. […]
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 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 […]
