As part of a carnival game, a =0.578 kgmb=0.578 kg ball is thrown at a stack of 25.3 cm25.3 cm tall, =0.363 kgmo=0.363 kg objects and hits with a perfectly horizontal velocity of ,i=12.3 m/s. vb, i=12.3 m/s. suppose the ball strikes the topmost object. immediately after the collision, the ball has a horizontal velocity of ,f=4.85 m/svb, f=4.85 m/s in the same direction, the topmost object has an angular velocity of =2.03 rad/sωo=2.03 rad/s about its center of mass, and all the remaining objects are undisturbed. if the object's center of mass is located =17.7 cmr=17.7 cm below the point where the ball hits, what is the moment of inertia of the object about its center of mass?

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
