What organs are part of the cardiorespiratory system? The cardiorespiratory system consists of the heart and blood vessels, which work with the respiratory system (the lungs and airways). These body systems carry oxygen to the muscles and organs of the body, and remove waste products, including carbon dioxide. Is 30 minutes of cardio 3 times […]
What is the basic source of magnetism?
What is the basic source of magnetism? The source of magnetism is the electric charges. The movement of the electric charge causes magnetism. Substances are made from tiny atoms. These atoms have protons, electrons and neutrons. Where is magnetism found? A very common source of magnetic field found in nature is a dipole, with a […]
Can a translation undo a reflection?
Can a translation undo a reflection? No. The translation followed by a reflection would put a figure in a different location in the plane when compared to the same reflection followed by the same translation. Summarize, or have students summarize, the lesson. We can sequence rigid motions. What does translation do to an image? Translation […]
Which climate zone has a short summer and is generally cold and windy?
Which climate zone has a short summer and is generally cold and windy? polar What are the 3 climate zones on Earth? The Earth has three main climate zones: tropical, temperate, and polar. The climate region near the equator with warm air masses is known as tropical. In the tropical zone, the average temperature in […]
What is the relationship between molecular motion and pressure?
What is the relationship between molecular motion and pressure? The greater the molecular motion, the greater the pressure the molecules exert. What is heat in terms of molecular motion? Molecules are in constant motion and so they possess kinetic energy. Molecules at a higher temperature have more kinetic energy i.e. they move faster. Heat is […]
What is a matrix material?
What is a matrix material? The matrix is basically a homogeneous and monolithic material in which a fiber system of a composite is embedded. It is completely continuous. The matrix provides a medium for binding and holding reinforcements together into a solid. What is the benefit of composite matrix? Advantages of Composite Materials Low cost […]
Is it more energy efficient to boil water?
Is it more energy efficient to boil water? An electric stove requires more energy and time to heat up, thus it takes longer to heat the water inside the kettle. However, an electric stove is more efficient in delivering energy to the kettle. Using boiling water and vinegar removes mineral deposits that reduce its energy […]
How should you approach a dock when there is a strong wind blowing away from the dock?
What is the chemical name of ch2?
What is the chemical name of ch2? Methylene Why is CH2 called methylene? Methylene was used as the name for methanol, which is wood alcohol, CH3OH, in the early 19th century. Methylene comes from methe + hyde the latter being the Greek word for wood, so methylene would mean wine from wood. What is full […]
What is average distance?
What is average distance? The average distance is the average shortest path of a graph, corresponding to the summa of all shortest paths between vertex couples divided for the total number of vertex couples. In quantitative terms, “high” and “low” are better defined when compared to the total number of nodes in the graph. How […]
