Answer:
electrons
Explanation:
An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma).

Answer:
The answer is
<h2>7,840,000 J</h2>
Explanation:
The kinetic energy KE of an object given it's mass and velocity can be found by using the formula

where
m is the mass
v is the velocity
From the question
m = 20000kg
v = 28 m/s
It's kinetic energy is

We have the final answer as
<h3>7,840,000 J</h3>
