(quiz 1, winter 2008) you are given a coaxial transmission line made of perfect electrically conducting cylinders of radii 1 r =1 cm and 2r =1.5cm . the space between the cylinders is filled with a material having the permittivity 0 ε = 4ε , permeability μ0 , and conductivity σ = 0 . the transmission line is terminated by a load zl at z = 0 . the transmission line is excited by:

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
