Answer:
1. Obelisk, tapered monolithic pillar, originally erected in pairs at the entrances of ancient Egyptian temples. The Egyptian obelisk was carved from a single piece of stone, usually red granite from tIn physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. he quarries at Aswān. ... While obelisks are known to have been erected as early as the 4th dynasty (c.
2. movement back and forth in a regular rhythm.
or
regular variation in magnitude or position about a central point, especially of an electric current or voltage.
"electromagnetic oscillations"
3. Rock crystal quartz is found widely distributed, some of the more notable localities being: the Alps; Minas Gerais, Brazil; Madagascar; and Japan. The best quartz crystals from the United States are found at HotSprings, Arkansas, and Little Falls and Ellenville, New York.
4. The first and most common way to write them is with lowercase “a.m.” and “p.m.” This way requires periods, and both Chicago Style and AP Style recommend this way of writing the abbreviations.
5 . The units and their physical quantities are the second for time, the metre for measurement of length, the kilogram for mass, the ampere for electric current, the kelvin for temperature, the mole for amount of substance, and the candela for luminous intensity.
6. In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
7. In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.
8. Speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled. A speedometer.
