Why do geostationary satellites have to be above the equator? It is always directly over the same place on the Earth’s surface. Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales. […]

How does the temperature of the gas relate to the motion of the particles?
How does the temperature of the gas relate to the motion of the particles? Temperature is related to particle motion because temperature increases the motion of particles when it is applied to an object. When you add thermal energy to an object, the particles either move faster (increased kinetic energy) or spread farther apart,(increased potential […]
What is cutting process in manufacturing?
What is cutting process in manufacturing? Definition. Cutting is manufacturing by removal of material (DIN 8580; CIRP Dictionary 2004). Particles of material, the chips, are mechanically removed from the raw material or from an unfinished part by cutting edges of a tool. Figure 1 shows some cutting processes (DIN 8589; CIRP Dictionary 2004). What was […]
What type of radiation does the sun emit the most?
What type of radiation does the sun emit the most? ultraviolet rays Which of the following types of radiation has the highest energy? Gamma rays Do Gamma rays reach Earth’s surface? The earth’s atmosphere absorbs the majority of ultraviolet, X-, and gamma rays, which are all shorter wavelengths than visible light. High energy X- and […]

What type of mercury is in thermometers?
What type of mercury is in thermometers? Elemental mercury is liquid at room temperature. It is used in some thermometers, dental amalgams, fluorescent light bulbs, some electrical switches, mining, and some industrial processes. It is released into the air when coal and other fossil fuels are burned. What are the parts of laboratory thermometer? The […]
What gives an airplane a forward force answer?
What gives an airplane a forward force answer? Explanation: Thrust is the force that is applied to the fuselage and air surfaces of an aircraft by the engine(s). When the plane needs to go down, the pilot reduces the thrust and gravity can overcome some of the lift the plane had resulting in a lower […]
