The direction of the magnetic field in an electromagnetic wave is: A. random, and not related to the direction of the electric field or the direction of propagation. B. anti-parallel to the electric field. C. parallel to the direction of propagation of the wave. D. parallel to the electric field. E. perpendicular to the electric field.
Explain in your own words what the meaning of domain is. Also, explain why a denominator cannot be zero. Find the domain for each of the two rational expressions below. Write the domain of each rational expression in set notation (as demonstrated in the example). Do both of your rational expressions have excluded values in their domains? If yes, explain why they are to be excluded from the domains. If no, explain why no exclusions are necessary. Incorporate the following...
Q)State and explain[ in your own words] the relationship between magnetic flux and magnetic flux density. State the governing equation.
Using your own words and complete sentences, explain why the density of the medium a wave propagates through affects the speed. Your explanation should include the effect of density on wave speed.
a) Explain in your own words what is meant by delocalized electrons. b) Draw all resonance structures for the nitrate ion.
Use your own words to explain what is subclinical and explain why are subclinical (also called “inapparent”) diseases significant for epidemiology and public health to a person who does not know epidemiology?
An electro magnetic wave has an electric field given by E=i(225 V/m) sin[(0.077 m^-1)z-(2.3*10^7 rad/s)t] **********Write down an expression for the magnetic field.
At one instance the electric field and the magnetic field at the origin are found to be E (1,0,0) and B (0,1,1). (a) What is the propagation direction of the wave? (b) Answer part a again if the values of E and B above are measured at r- (1,0,1) instead. 3.
