How did the railroad influence European colonial powers in the 19 century A uniform plane wave with parallel polarization is propagating in a lossless dielectric medium (l is 1), and is incident obliquely onto a plane boundary with another lossless dielectric medium (u 2, E 2). (30%) (a) Derive the Snell's laws of reflection and refraction in terms of the refractive indices and angles. (b) Derive the general expressions for the reflection and the transmission coefficients of the EM field. Find such expressions in terms of the refractive indices if both media are nonmagnetic, i.e., M F M 240. (c) Derive the general expression for the Brewster angle. Find such an expression in terms of the refractive indices if both media are nonmagnetic. (d) Prove that, under the condition of no reflection, the sum of the Brewster angle and the angle of refraction is 90 if both media are nonmagnetic. (e) For total reflection to occur, find the condition for the medium property and the critical angle. nate is lifting weights to build muscle for the upcoming football season. while nate is in the gym lifting, a group of cheerleaders comes in to start practice. while the cheerleaders were watching, nate was able to do 10 reps more than he has ever accomplished in the past. this best illustrates: The poll tax, the literacy test, and the actions of the ku klux klan were all attempts to limit the effectiveness of which action taken by the federal government? Which equations are true for x = 2 and x = 2? Select two options O x2 4 = 0 O x2 = 4 O 3x2 + 12 = 0 O 4x2 = 16 O 2(x 2)2 = 0 When researchers in Australia studied older and middle-age skateboarders, it was found that the skaters used Let f:RS be a surjective homomorphism of rings with identity.(a) If R is a PID, prove that every ideal in S is principal.(b) Show by example that S need not be an integral domain. How is consciousness different to sub-consciousness ?

A cryotherapy chamber uses extreme cold to reduce muscle soreness. A chamber is currently 0F. The temperature in the chamber is dropping 2.5F every second. Identify an inequality that represents the numbers of seconds $s$ that can pass for the temperature to drop below -20 F Can anyone solve this proof? 1. a 1.4 x 103 kg car is westbound at a velocity of 37.0 km/h when it collides with a 2.0 x 103 kg truck northbound at a velocity of 35 km/h. if these two vehicles lock together upon collision, what is the initial velocity of the vehicles after collision? (7.2 m/s 37o w of n) 2. a 6.2 kg object heading north at 3.0 m/s collides with an 8.0 kg object heading west at 3.5 m/s. if these two masses stick together upon collision, what is their velocity after collision? (2.4 m/s 56o w of n) 3. a 4.0 x 104 n truck moving west at a velocity of 8.0 m/s collides with a 3.0x104 n truck heading south at a velocity of 5.0 m/s. if these two vehicles lock together upon impact, what is their velocity?(5.0 m/s 25o s of w) The diagram below represents a wave.What is the speed of the wave if its wavelength is 3.0 m?
