Answer 2

Answer:

The convection current when an electron density of 200 units is traveling at a speed of 12m/s is 2400 units.

Explanation:

• A convection current is a process that involves the movement of energy from one place to another. Convectional heat transfer is another name for it.

• The convection current density is given by the following equation,

                                      $\mathrm{J = \rho ev}$     (1)

Where,

J=convection current

ρ=electron density

e=charge on an electron

v=speed with which the electron is traveling

From the question we have,

The electron density(ρe)=200 units

The speed at which the electrons are traveling (v)=12m/s

By plugging the numbers into equation (1), we arrive at this;

                                $\mathrm{J = 200\times 12}$

                                $\mathrm{J = 2400\ units}$

So, the convection current when an electron density of 200 units is traveling at a speed of 12m/s is 2400 units.
