Which factor is responsible for blood clotting? The clotting factors are Factor I (fibrinogen), Factor II (prothrombin), Factor III (tissue thromboplastin or tissue factor), Factor IV (ionized calcium), Factor V (labile factor or proaccelerin), Factor VII (stable factor or proconvertin), and Factor VIII (antihemophilic factor). What are the factors that affect clotting time? In the […]

Is Black an absence of light? All other colors are reflections of light, except black. Black is the absence of light. Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create […]

What is water cycle in short? The water cycle is the path that all water follows as it moves around Earth in different states. Water vapor—a gas—is found in Earth’s atmosphere. Water can be found all over Earth in the ocean, on land and in the atmosphere. The water cycle is the path that all […]

What are profiling techniques? Offender profiling (also known as psychological profiling) refers to a set of investigative techniques used by the police to try to identify perpetrators of serious crime. It involves working out the characteristics of an offender by examining the characteristics of the crime scene and the crime itself. What are profiling tools? […]

Why do wires get hot resistance? Heating a metal conductor makes it more difficult for electricity to flow through it. These collisions cause resistance and generate heat. Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. What causes low resistance in […]

Is wattage important for hair dryer? Wattage does matter, but only to an extent: The amount of power put in, the more power you get out. While a high power or salon dryer uses more energy, that’s not necessarily the best form of measurement in terms of quality. A blow dryer may use high wattage […]

How do you calculate GPE? So to get the GPE of an object you need a formula, the formula is MASS X GRAVITY X HEIGHT (M X G X H). How does speed affect kinetic energy? It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 […]

What happens to the direction of the magnetic field about an electric current when the direction of the current is reverse? What happens to the direction of the magnetic field about an electric current when the direction of the current is reversed? The magnetic field reverses direction at every point. A clockwise pattern of concentric […]
