What is a vector vector example?
What is a vector vector example? A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight. What is called a vector give one example? […]
Why is the electric field of dipole not zero?
Why is the electric field of dipole not zero? Why is electric field of dipole nonzero? Because the positive and the negative charges are separated by some distance. So though the a Gaussian surface enclosing the electric dipole has zero net charge the electric field in the region isn’t zero because there are separated charges […]

How do you find boiling point with temperature and pressure?
How do you find boiling point with temperature and pressure? If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures. What […]
