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 […]
Can cotton be used for insulation?
Can cotton be used for insulation? Cotton is non-allergenic and adaptable; it insulates and absorbs more cost effectively than any synthetic or artificial fabric. Cotton is used in warm climates because it wicks moisture away from the skin. It is worn in layers of waffled fabric in cold climates to insulate. Why is distilled water […]

What torque should I use for screws?
What torque should I use for screws? Setting 1 is low speed/high torque and is best for driving screws. Setting 2 is a medium speed/torque and can be used for drilling or driving. Setting 3 is the highest speed and is meant for drilling or driving fasteners. Does length of screwdriver matter? A: This may […]
What are the chemical properties of benzene?
What are the chemical properties of benzene? Benzene has a boiling point of 80.1 °C (176.2 °F) and a melting point of 5.5 °C (41.9 °F), and it is freely soluble in organic solvents, but only slightly soluble in water. What are the physical properties of phenol? Phenols are similar to alcohols but form stronger […]
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 […]
What qualifications do you need to be an astrophysicist?
What qualifications do you need to be an astrophysicist? You would need a degree in astronomy or astrophysics. For entry, you generally need 4-5 Highers including Maths, Physics and usually another science subject. You then need to do specialist postgraduate study, usually a PhD, to get a post as a professional research astronomer. Does NASA […]
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?
