Jane smith, an old‐fashioned engineering student, believes that the boiling of water is best suited for use as the reference point on temperature scales. unhappy that the boiling point corresponds to some odd number in the current absolute temperature scales, she has proposed a new absolute temperature scale that she calls the smith scale. the temperature unit on this scale is smith, denoted by ܵ, and the boiling of water on this scale is assigned to be 1000 ܵ. from a thermodynamic point of view, discuss if it is an acceptable temperature scale. also, determine the freezing point of water in the smith scale and obtain a relation between the smith and the celsius scales.

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
