Cotton fibres come from cotton plants, and this fibre is then processed by mankind into useful products.
By producing electricity
The three primary sources of electromagnetic fields (EMF) are natural sources, such as the Earth's magnetic field and cosmic radiation; man-made sources, including power lines, electrical appliances, and telecommunications devices; and industrial sources, which encompass equipment like transformers and generators used in various sectors. Each of these sources emits EMF at varying frequencies and intensities, impacting both the environment and human health. Understanding these sources is crucial for assessing exposure and potential risks.
some of the sources of r in the s a and d p. are man u and man city plus all of the real and barcelone players!
wood made by man!
Both. Some kinds are natural and some man-made.
Natural light sources, like the sun, produce light through natural processes, while artificial light sources, like light bulbs, are man-made and produce light through electricity.
The ozone can be damaged by natural or man made sources. Man made is CFC's and natural is UV rays.
Both. Some kinds are natural and some man-made.
electricity
Man-made light sources... lamp, torch, LCD etc.
Yes, current electricity is more useful than static electricity because it can be controlled and directed through wires to power devices. Current electricity flows continuously in one direction in a circuit, allowing for predictable and controllable use in various applications.
Natural sources of these gases include volcanic eruptions, wildfires, and decomposition of organic matter. Man-made sources include burning fossil fuels, industrial processes, and deforestation. Both natural and man-made sources contribute to the levels of these gases in the atmosphere.
Electricity is a natural phenomenon that can be harnessed and utilized by humans for various purposes. Man-made systems, such as power plants and electrical grids, help generate and distribute electricity for our use.
like battery or circuits
Electric bulbs, fluorescent lamps, and LED lights are three examples of man-made sources of light commonly used in indoor and outdoor settings.
