Answer:




Explanation:
The electrical reactance is defined as:

Where:

So, replacing the data provided by the problem:

Now, the impedance can be calculated as:

Where:

Replacing the data:

In order to find the magnitude of the impedance we can use the next equation:

We can use Ohm's law to find the current:

Therefore the current is:

And its magnitude is:

Finally the phase angle of the current is given by:

I believe it is true . Somebody correct me if I’m wrong!
Answer:
the average drift speed of the mobile electrons in the metal is 1.089 x 10⁻⁴ m/s.
Explanation:
Given;
mobility of the mobile electrons in the metal, μ = 0.0033 (m/s)/(N/C)
the electric field strength inside the cube of the metal, E = 0.033 N/C
The average drift speed of the mobile electrons in the metal is calculated as;
v = μE
v = 0.0033 (m/s)/(N/C) x 0.033 N/C
v = 1.089 x 10⁻⁴ m/s.
Therefore, the average drift speed of the mobile electrons in the metal is 1.089 x 10⁻⁴ m/s.
