What is meant by rotational motion? When an object moves in a straight line then the motion is considered as translational but when the same object moves along an axis in a circular path then it is known as Rotational Motion. What is the formula of rotational motion? ω = ω 0 + α t […]
Does a chemical reaction occur when boiling water?
Does a chemical reaction occur when boiling water? Answer and Explanation: No, boiling water is NOT a chemical reaction, but it is a physical change. When water, H2 O, is in liquid form, it can be heated to a boil. Is Steam a chemical reaction? A physical reaction causes the matter to shift shape or […]
Is monoculture good or bad?
Is monoculture good or bad? Higher Revenues. By growing monoculture plants, farmers usually benefit from higher profits. For example, cultivating a single kind of crop that is best suited to development in specific climate conditions, allows the farmer to get better yields and, therefore, get higher income. Is monoculture farming sustainable? And the approach to […]
How should one interpret data presented in a graph?
How should one interpret data presented in a graph? Answer: To interpret a graph or chart, read the title, look at the key, read the labels. Then study the graph to understand what it shows. Which chart should I use? Bar charts are good for comparisons, while line charts work better for trends. Scatter plot […]
Where are stopwatches used?
Where are stopwatches used? Its first use was in ski racing but was later used by the World University Games in Moscow, Russia, the U.S. NCAA, and in the Olympic trials. The device is used when time periods must be measured precisely and with a minimum of complications. Laboratory experiments and sporting events like sprints […]
What are the two functions of the muscular system?
What are the two functions of the muscular system? The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function of movement is the muscular system’s second function: the maintenance […]
Do Hurricanes have eyes?
Do Hurricanes have eyes? The most recognizable feature found within a hurricane is the eye. They are found at the center and are between 20-50km in diameter. It is actually the calmest section of any hurricane. The eye is so calm because the now strong surface winds that converge towards the center never reach it. […]
What color dissipates heat the fastest?
What color dissipates heat the fastest? black What material stays cool in the heat? Since then, they and other researchers have made a host of materials, including films, spray paints and treated wood, that stay cool in the heat. These materials all rely on enhancing a natural heat-shedding effect known as passive radiative cooling. What […]
What is the differences between deposition and erosion?
What is the differences between deposition and erosion? Erosion is the process by which natural forces move weathered rock and soil from one place to another. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. What is […]
Does viscosity depend on nature of liquid?
Does viscosity depend on nature of liquid? The viscosity is calculated in terms of the coefficient of viscosity. The value of this coefficient constant for a liquid depends on its liquid’s nature. What is the viscosity coefficient of liquid? Enter your search terms: The ratio of the shearing stress to the velocity gradient is a […]
