Answer:

Resistivity (rho) = Resistance (G) * Area (\pi r^2) / Length (nm)

Explanation:

if rho is the resistivity, then according to the proper equation re-arrangement the resistance is G. Then, Area can be calculated by radius and dividing their product by the length of channel.

A beam of electrons is sent horizontally down the axis of a tube to strike a fluorescent screen at the end of the tube. On the w
slamgirl [31]

Answer:

The answer is 3.

Explanation:

The answer to this question can be found by applying the right hand rule for which the pointer finger is in the direction of the electron movement, the thumb is pointing in the direction of the magnetic field, so the effect that this will have on the electrons is the direction that the middle finger points in which is right in this example.

So as a result of the magnetic field directed vertically downwards which is at a right angle with the electron beams, the electrons will move to the right and the spot will be deflected to the right of the screen when looking from the electron source.

I hope this answer helps.
