073714) {Wave on a String} In this question you will explore waves on a string using an online simulation found here. Image size: SMLMax Part a (1 points) First, we will figure out the speed of the wave at maximal tension. 1) Set the mode (upper left corner) to Pulse 2) Set the end conditions (upper right corner) to Fixed End. 3) Set the Damping slider to 0. 4) Set the Tension slider to high (as far as it will go) 5) Set the Amplitude slider to high (as far as it will go). 6) Turn on the Rulers and Timer (check the corresponding boxes) 7) Set the simulation to Slow Motion 8) Hit the Pause button (big blue circle in bottom center). Turn on the timer and click the green circular button to start a wave pulse. Stop the timer when the wave pulse first hits the end of the string (when the final bead first starts to move). Do this a couple times to get a precise measurement of the time it took the wave pulse to cross the string. What is the wave velocity

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
