Write the (real) electric and magnetic fields for a monochromatic plane wave of amplitude Eo, frequency ω, and phase angle zero that is
(a) traveling in the negative x direction and polarized in the z-direction;
(b) traveling in the direction from the origin to the point (1,1,1), with polarization parallel to the xz plane. In each case, sketch the wave, and give the explicit cartesian components of k^ and n^.
From the ground a projectile is fired with a velocity of 30m/sat 30 degrees above the horizontal. How long will the projectile take to return to the ground
A racecar travelling at a constant speed turns in a circle with a radius of 10 m. what is the racecar's speed
What do we mean when we say that an object is charged and What do we mean when we say that the net charge is conserved in a closed system?
A solenoid 85.0 cm long has a cross-sectional area of 22.0 cm2. It has 1000 turns of wire, and is carrying a current of 6.60 A. What is the magnetic field inside the solenoid
An infinite rod has a charge density of 5.00 nC/m. What is the strength of the electric field at a distance of 3.50 m from the rod
A turbulent boundary layer is studied in a zero pressure-gradient flow on a flat plate in a laboratory. Atmospheric air at 20-C flows over the plate at 10 m=s. How far from the leading edge can turbulence be expected.
A ball is thrown directly upward with an initial velocity of 10 m/s. how long is the ball in the air
A transparent rod 50.0cm long and by a refractive index of 1.60 is cut flat at the right end and rounded to hemispherical surface (convex) by a radius of 15.0cm at the left end. An object is placed on the axis of the rod 12.0cm to the left of the ver..
In a refrigerator, heat is transferred from a colder area (theinside of the refrigerator) to a warmer area (the air outside ofthe refrigerator). Given what you know about internal energy,explain how this is possible.
The 2.00 kg object below is released from rest at the height of 5.0 m on a curved frictionless ramp. At the foot of the ramp is a spring of force constant k = 450 N/m. The object slides down the ramp and into the spring, compressing it a distance x b..
