The length of an axon is 10 mm, and its time constant is 4 msec. a voltage change at one end of the axon is 120 mv, which results in a change of about 10.35 mv at the opposite end after 4 msec. given this information, what is the length constant of the neuron? ( input answer in mm, rounded to the nearest whole number, without including the units.)
2) if the diameter of an axon is decreased, and the amount of ion channels stays the same causing membrane resistance to be largely unchanged, what would happen? (state all that apply.)
the length constant increases.
the length constant decreases.
the time constant increases.
the time constant decreases.

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
