    • What Causes Earthquakes?

      What Causes Earthquakes?

      An earthquake is caused when two blocks or plates of the Earth slip past each other in the lateral, vertical, or a combination of directions in a sudden manner. Due to the large pressures that develop between the Earth’s plates along fault lines at the Earth’s surface, one of the bodies will eventually give way.

    • What Causes Radioactivity?

      What Causes Radioactivity?

      Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In other words, radioactivity is the

    • What Causes Evaporation?

      What Causes Evaporation?

      When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process

    • Linear Actuator

      Linear Actuator

      A linear actuator is a mechanical device that makes a linear motion, usually via a hydraulic pump or electromagnetic gear. Other forces can be used to create linear motion. The different types of linear actuators include screw, wheel and axle, cam, hydraulic pump, pneumatic, piezoelectric, and electro-mechanical. Linear motors, wax motors, and telescoping linear actuators

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Zettabyte


      A zettabyte describes a unit of data or information that is equal to 1,000,000,000,000,000,000,000 bytes. The term is equal to a billion terabytes and the symbol ZB represents it. Zebibyte (ZiB) describes a measurement of data using the power of 1024. A single zettabyte is equivalent to 1,024 exabytes and is used prior to the

    • What Causes Lightning?

      What Causes Lightning?

      Lightning can be described as a massive discharge of electrical energy that can reach the speed of 130,000 mph and can exceed temperatures of 30,000 degrees Celsius. Although we know a lot about this phenomenon, it is still unclear how and why lightning forms. We will mention some of the theories on how lightning is

    • The Venturi Effect

      The Venturi Effect

      The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase. The effect is mathematically described through the Bernoulli equation and can be observed in both nature and industry. Many industry applications rely on

    • Total Harmonic Distortion

      Total Harmonic Distortion

      Total Harmonic Distortion (THD) is a measured difference in audio levels between the input audio signal’s harmonics and the harmonics of the output audio signal of an amplifier or other audio device. Output Distortion Level As the signal passes through an amplifier it is always somewhat distorted at its output. The waveform at the input

    • How Magnets Work

      How Magnets Work

      A magnet is an object formed out of any type of material that can produce its own magnetic field. Such materials include hard magnets and soft magnets. Examples of hard magnets are neodymium magnets and refrigerator magnets which always remember the way in which they were magnetized.Examples of soft magnets are electromagnets, which can be
