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 […]
What are the negatives of fossil fuels?
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. […]

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 […]
Does milk stay hotter water?
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 […]
What is dew attack?
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 […]
How are position and speed useful for describing the motion of an object?
How are position and speed useful for describing the motion of an object? How are position and speed useful for describing the motion of an object? Speed describes where the object is going while position explains where the object is currently. Velocity is speed with direction. Velocity describes where an object is going. How useful […]
What are the factors that influence the rates of weathering and erosion?
What are the factors that influence the rates of weathering and erosion? Rainfall, heat and moisture are the 3 main factors which affect the rate of weathering and soil erosion. Weathering happens more quickly in hot and wet climates. Wind is another major factor affecting soil erosion. What are the factors that affect the rate […]
