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 […]
How the nervous system works with the circulatory system?
How the nervous system works with the circulatory system? The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate […]
Can I use Styrofoam as insulation?
Can I use Styrofoam as insulation? A lot of the merchandise on store shelves ship in Styrofoam, but the material doesn’t smash down, taking up lots of valuable space. Styrofoam is also a material that has great insulating properties. Can you spray foam over electrical wires? Yes, expanding spray foam can damage electrical wiring. Careful […]
Is being too detail oriented a weakness?
Is being too detail oriented a weakness? Being detail-oriented is typically a good thing, but if you’re someone who tends to spend too much time on the specifics of a project, it could also be considered a weakness. Example: “My greatest weakness is that I sometimes focus too much on the details of a project […]
What will happen if tectonic plates are not moving?
What will happen if tectonic plates are not moving? One big problem with plate tectonics stopping is that plate motion is the mechanism by which Earth is cooling down and getting rid of its internal heat. If the plates stopped moving, the planet would have to find a new and efficient means to blow off […]
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 […]
What are the two categories of self-concept?
What are the two categories of self-concept? The self-categorization theory developed by John Turner states that the self-concept consists of at least two “levels”: a personal identity and a social one. In other words, one’s self-evaluation relies on self-perceptions and how others perceive them. What are the three parts of self-concept? Self-concept is an individual’s […]
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 […]
What is the relation between force and dielectric constant?
What is the relation between force and dielectric constant? Dielectric constant of a medium is defined as the ratio of forces between two charges placed in vacuum to medium without any change in magnitude of charges and their distance. Therefore, as K decreases there will be an increase in force. Why is force inversely proportional […]
