What is the fundamental frequency of a string? The frequency f = 1/T = v/λ. So f = v/λ. We also saw that, for the fundamental frequency f1, the string length is λ/2, so f1 = v/2L. The wave speed is determined by the string tension F and the mass per unit lenght or linear […]

Does milk stay hotter water? Water has higher specific heat capacity (around 4.2 J/g °C) than milk (around 3.9 J/g °C). So, because milk has lower specific heat capacity than water, for the same amount of heat energy released, the decrease in the temperature of milk will be greater than that of water. How can […]

Where are joints found in the body? The main joints of the body — such as those found at the hip, shoulders, elbows, knees, wrists, and ankles — are freely movable. They are filled with synovial fluid, which acts as a lubricant to help the joints move easily. Which is the most common type of […]

How do you display data visually? How to present data visually (data visualization best practices) Avoid distorting the data. Avoid cluttering up your design with “chartjunk” Tell a story with your data. Combine different types of data visualizations. Use icons to emphasize important points. Use bold fonts to make text information engaging. What are the […]

What is 8.54 rounded to the nearest tenth? Answer Expert Verified. The nearest tenth of a number is the first decimal. As can be seen, 8.54 has two decimals, so we must round the first one. If the second decimal was 5 or bigger than 5, then the first decimal would be increased by 1, […]

What are the negatives of fossil fuels? Fossil fuel cons Fossil fuels are not renewable energy sources. If we do not reduce consumption, we will run out of them, very quickly. Fossil fuels pollute the environment. In the case of irresponsible use, they can be dangerous. Easier to store and transport. It is really cheap. […]

What is dew attack? A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy, including laser, microwaves, and particle beams. Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices. What’s a dew? The condensed water is called dew when it forms on a […]

Are .gov sites credible? gov = Government. All branches of the United States federal government use this domain. Information such as Census statistics, Congressional hearings, and Supreme Court rulings would be included in sites with this domain. The information is considered to be from a credible source. Which of these is the most credible Internet […]

What is the moment of inertia of a rod of mass m and length L? We know that the moment of inertia about an axis perpendicular to the rod and passing through its centre is ML212. Now we need to M.O.I about an axis through its edge and perpendicular to the rod. Hence, the correct […]
