How do I know when my electricity will come? Get in touch with the local network operator that manages the electricity wires in your area. They can tell you more about the power cut, and when you can expect your power to come back on. How to contact your network operator: Go to your local […]
What is the hydrosphere made of?
What is the hydrosphere made of? The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground—as groundwater, in […]
Why is there no electrostatic force between two neutral objects?
Why is there no electrostatic force between two neutral objects? The negative/positive charges don’t want to be clumped together in one place if they can help it. But a neutral object does not have a net charge, so it cannot separate the charges in another neutral object. What happens when a positively charged object is […]
What happens when 2 magnets are forced together?
What happens when 2 magnets are forced together? When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. What is the most likely outcome it will become a permanent magnet? A magnetically soft material is placed in a […]
What is the yield when you turn left at an intersection?
Why do electrons transfer from a sweater to a balloon?
Why do electrons transfer from a sweater to a balloon? Since electrons have a negative charge, the balloon now has a negative charge. But the sweater fibers lost some of their electrons, so now the fibers have a positive charge (they have more protons than electrons). Positive and negative attract so if you bring the […]
What nervous system has no positive effects?
What nervous system has no positive effects? Exercise has no positive effects on the nervous system. Physical activity is the movement of large muscle groups through daily activities. How physical activity improves our daily living? Physical activity or exercise can improve your health and reduce the risk of developing several diseases like type 2 diabetes, […]
What is general relativity simple definition?
What is general relativity simple definition? What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it. What […]
Why does a metal spoon feel colder than a wooden spoon?
Why does a metal spoon feel colder than a wooden spoon? Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. It is because the metal conducted heat faster that it feels colder than the wood, which conducted […]
Can flattened into thin sheets?
Can flattened into thin sheets? Malleability is a substance’s ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Can be flattened into thin sheets answer? Answer : (a) The property of […]
