In which medium will a sound wave move more quickly? Sound waves travel faster and more effectively in liquids than in air and travel even more effectively in solids. What makes sound when two things collide? The fact that sound is a form of energy is most obvious when two objects collide; they lose some […]
What is the force between two electrons separated by 1 um?
What is the force between two electrons separated by 1 um? The mass of an electron is 9.1094*10^(-31) kg and its charge is 1.6022*10^(-19) coulombs. Their separation 1 micrometre ( 1 UM) or 10^(-6) m. So the force of repulsion is (1.6022*10^(-19))^2/[4*pi*(4*pi*10^(-7))*10^(-12)] = 1.6256*10^(-21) newtons. What is K in Coulomb’s law? The symbol k is […]
How does heat transfer in water or air?
How does heat transfer in water or air? Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and […]
What is the use of PV diagram?
What is the use of PV diagram? A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology. What does P equal in PV nRT? Ideal Gas Law PV=nRT. where P = pressure […]
