Maxwell's electromagnetic equations in a vacuum are given by; ob (faraday's law) (ampere's law), ▽ . e = 0 (gauss's law), ▽·b-0 (gauss's law for magnetism). 1 oe ▽ x b =-- where e - e(x, y, z, t) and b - b(r, y, z, t), are the electric and magnetic fields, and where c is the speed of light respectively (a) using the equations above, prove (b) prove the following vector calculus identity in r3, where f is a twice continuously differentiable vector field where v72 is the vector laplacian given by (c) hence derive the electromagnetic wave equation 02

Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (mpg). heavier cars tend to have lower fuel efficiencies (lower mpg ratings). which variable (weight or fuel efficiency) is most naturally considered the explanatory (predictor) variable in this context?

Name the non metal condut electricity

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
