An irregular lump of an unknown metal has a measured density of 4.64 g/ml. the metal is heated to a temperature of 153 °c and placed in a graduated cylinder filled with 25.0 ml of water at 25.0 °c. after the system has reached thermal equilibrium, the volume in the cylinder is read at 31.0 ml, and the temperature is recorded as 45.9 °c. what is the specific heat of the unknown metal sample? assume no heat is lost to the surroundings.

for this one it would be d bump/forearm pass

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
