What causes resistance in a wire?
What causes resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. […]

Why is gravity a non-contact force?
Why is gravity a non-contact force? Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the […]
What is the main cause of ozone depletion?
What is the main cause of ozone depletion? Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity. Is inhaling ozone bad? Whether in its pure […]
How do you interpret mean median and mode in research?
What are the possible values of n and ML for an electron in a 4 d orbital?
What happens when a solid is dissolved in a liquid?
What happens when a solid is dissolved in a liquid? In the simplest case it involves mixing two materials together. The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. Why […]
