A 0.5530 kg ice cube at − 12.40 °C is placed inside a chamber of steam at 365.0 °C. Later, you notice that the ice cube has completely melted into a puddle of water. If the chamber initially contained 6.910 moles of steam (water) molecules before the ice is added, calculate the final temperature of the puddle once it settled to equilibrium. Assume the chamber walls are sufficiently flexible to allow the system to remain isobaric and consider thermal losses or gains from the chamber walls as negligible.

50 inches should be the resultant vector

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
