A few months ago, you re-potted several different types of house plants to larger pots because the plants had outgrown their current pots. You used the same bagged soil for all of the plants and placed them in the same location, yet one of them appears to be dying after a few weeks. Which of the following factors could be causing the problem with the plant? nutrients in soil

none of the above

temperature

amount of water

b would be the answer

the total distance traveled by the car is

30km + 49km = 79 km .

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
