Answer:
electric current
Explanation:
<em>An electric current is defined as the movement or flow of electrically charged particles in a particular direction either within an electric circuit or an electrolytic cell. </em>
In an electric circuit, the electrically charged particles are called electrons while in an electrolyte, they are referred to as ions.
The force exerted by the laser beam on a completely absorbing target is .
The given parameters;
- <em>power of the laser light, P = 1050 W</em>
- <em>wavelength of the emitted light, λ = 10 μm </em>
The speed of the emitted laser light is given as;
v = 3 x 10⁸ m/s
The force exerted by the laser beam on a completely absorbing target is calculated as follows;
P = Fv
Thus, the force exerted by the laser beam on a completely absorbing target is .

The correct answer is A. True.
I hope this helps.
Have a great day by the way. :)
As per Coulomb's law we know that force between two charges is given as
here we know that
now from above formula we will have
so they will attract towards each other as they are opposite in nature with force F = 4500 N
Answer: v = √(30.1² + 2(9.81)(14.7)) = 34.560... ≈ 34.6 m/s
