<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
Answer:
Weathering and erosion, transportation, deposition, compaction and cementation, metamorphism, and rock melting.
Explanation:
The rock cycle has 5 main sections (igneous, sedimentary, sediment, metamorphic, and magma.) The rock cycle can go almost any way it wants. Its not like the water cycle were it goes in certain order.
Answer:
Explanation:
En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.
Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1 la palabra está relacionada con māter («origen, fuente, madre»)2 y se corresponde con el griego hyle3 (de hylos: «bosque, madera, leña, material»)45 que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6
El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.
Answer:
The correct answer will be option- B.
Explanation:
Synovial fluid is a clear slippery fluid which is present in the synovial cavity.
The synovial fluid helps the nourishment as it provides nutrients to the and oxygen to the hyaline cartilage of the bones as well as the lubrication of the cartilage surfaces due to the viscous nature like oil which lubricates the piston.
This smooth surface facilitates the smooth and painless movements between the bones, therefore, the Option-B is the correct answer.
