Absolute location is a place's exact spot on a map, while relative location is an estimate of where a place is in relation to other landmarks. Absolute location is defined by latitude and longitude measurements. Relative location is used in conversational language and for giving rough directions.Know More
Absolute and relative location are two common methods of relating where streets, cities, stores and other important places are found on Earth. These systems of measurement are sympathetic to one another, with relative locations defined by their distribution around absolute locations on a map.
Absolute locations are used for scientific measurements. They are essential for cartography, meteorology and sciences that rely on the placement of physical landmarks on the Earth's surface to make accurate predictions or generate clear conclusions. Even astrology and space exploration need absolute location and technology tied to them to make flights and exploration successful.
Relative locations are more colloquial and defined by their relation to other places. These are not scientific or absolute measurements, but they do offer familiarity and ease of understanding. That makes them especially important for giving directions or remembering routes. Relative locations make it easy to associate places with one another in a way that generates a personal map of a landscape.Learn more about Motion & Mechanics
Sound varies from low to high pitch in direct relation to the frequency of the sound wave. Sound waves oscillate, and the number of times per second a sound wave oscillates is known as its frequency. A higher frequency produces a higher pitch, while a lower frequency results in a lower pitch.Full Answer >
A plumb bob is a pendulum commonly used by construction workers and surveyors to accurately locate the levels over a specific spot on the Earth?s surface. Inertial guidance systems on some aircraft instrumentation, missile guidance systems and seismographic instruments all use a modification of the pendulum. The Foucault pendulum is a special pendulum used to demonstrate the Earth?s rotation.Full Answer >
A truss consists of a set of members that act in compression or tension as a unit, and truss bridges stay up because of the forces that pull outward on the ends of the tension member, forming a triangular structure that keeps the bridge in place. A triangle is the ideal shape to hold this tension because a triangle does not experience distortion from the pushing and pulling of stress.Full Answer >
The Krebs cycle, also known as the citric acid cycle and the tricarboxylic acid cycle, is the central metabolic pathway that takes place in the mitochondrion and breaks down all metabolites, including sugars, fatty acids and amino acids. The cycle is named after German-born British physician and biochemist Hans Adolf Krebs, who identified the citric acid cycle in the human body while working at the University of Sheffield in 1937.Full Answer >
