Water vapor enters an adiabatic nozzle operating horizontally and at steady state. The water enters with velocity of 200 [m/s] and specific enthalpy of 3394.2 [kJ/kg]; it exits with specific enthalpy of 3000 [kJ/kg]. The exit velocity is most nearly

the first step is making objective observations.

they have to be based on a certain event and can be confirmed by others if it is right or not.

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

i think the answer is tomato juice? not entirely sure though
