Kelvin, c. mean, d. model, e. precision, f. range, g. scientific notation | c | DD_0215 | image | teaching_images/waves_7678.png | This diagram represents a sound wave and its characteristics. The peak of a wave is called compression or crest. The valley of a wave is called rarefaction or trough. Wave length is the length between two consecutive peaks, i.e. crest or two consecutive valleys, i.e. trough of a wave. Louder sound has shorter wavelength and softer sound has longer wavelength. Magnitude of maximum disturbance on either side of the normal position or mean value in a medium is called amplitude. In other words, amplitude is the distance from normal to the crest or trough. Time required to produce one complete wave is called time period or time taken to complete on oscillation is called the time period of the sound wave. The number of sound waves produced in unit time is called the frequency of sound waves. Frequency is the reciprocal of the time period of wave. Distance covered by sound wave in unit time is called the velocity of sound wave. | 0.257046 |

Kelvin, c. mean, d. model, e. precision, f. range, g. scientific notation | d | DD_0121 | image | teaching_images/life_cycles_357.png | The diagram shows the life cycle of organisms in the Animal kingdom called Arthropods. Arthropods are invertebrates in Phylum Arthropoda. There are more than a million known species of arthropods. In addition to insects, arthropods include animals such as spiders, centipedes, and lobsters. Arthropods reproduce sexually. Male and female adults produce gametes or eggs. If fertilization occurs, eggs hatch into offspring. After hatching, most arthropods go through one or more larval stages before reaching adulthood. The larvae may look very different from the adults. They change into the adult form in a process called metamorphosis. During metamorphosis, the arthropod is called a pupa. It may or may not spend this stage inside a special container called a cocoon. A familiar example of arthropod metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult). Each life stage can evolve adaptations to suit it for its specific functions without affecting the adaptations of the other stages. In some arthropods, newly hatched offspring look like small adults. These arthropods don't go through larval stages. They just grow larger until they reach adult size. | 0.28278 |

Thats because state of matter is a physical property. As a result, when matter changes state, it doesnt become a different kind of substance.

Kelvin, c. mean, d. model, e. precision, f. range, g. scientific notation | e | DD_0015 | image | teaching_images/ocean_waves_7117.png | This diagram illustrates the components and behavior of a wave propagating through water. The highest point in a wave is called the Crest, whereas the lowest point is called the Trough. Waves are periodic, meaning they maintain the same pattern as they propagate. The distance from one crest to another is called the Wavelength. The wavelength can also be measured from any point in the wave to the next point at the same elevation. Beneath the wave crests, water molecules tend to move in an orbital path. Two important properties of a wave are its Frequency and Period. The frequency of a wave is related to how fast the wave is moving. Frequency is defined as the number of times a particular point in a wave, say a crest, passes by a given point each second. Period is defined as the time it takes for a wave to move through one wavelength or cycle. | 0.25523 |

Troposphere is the shortest layer closest to Earth's surface at about 15km away from the surface. The stratosphere is the layer above the troposphere and rises to about 50 kilometers above the surface. The mesosphere is the layer above the stratosphere and rises to about 80 kilometers above the surface. Temperature decreases with altitude in this layer. The thermosphere is the layer above the mesosphere and rises to 500 kilometers above the surface. The International Space Station orbits Earth in this layer. The exosphere is the layer above the thermosphere. This is the top of the atmosphere. | 0.252964 |

Because fluid flows from an area of high to low pressure, the drink moves up the straw and into your mouth. When you breathe, a muscle called the diaphragm causes the rib cage and lungs to expand or contract. When they expand, the air in the lungs is under less pressure than the air outside the body, so air flows into the lungs. When the ribs and lungs contract, air in the lungs is under greater pressure than air outside the body, so air flows out of the lungs. | 0.248976 |
