<span>Answer: option C. the presence of free-flowing ions.
</span><span />
<span>Explanation:
Ionic compounds dissociate in water forming solutions with free ions. The solution conducts electricity and is named electrolyte.
</span><span />
<span>The ions are species with charge: cations are ions with positive charge and anions are ions with negative charge.
</span><span />
<span>The ions become the carrier of the charge so they are the responsible for the flow of current.
</span><span>
</span><span>
</span><span>So as the electrons are the carriers of the charge in the solid conductors (copper, aluminun, and others), the ions are the carriers of the charge in solutions.</span><span /><span>That is how the the electrolyte solutons conduct electricity.</span>
Center of the solar system
Answer:
This is because an instrument literally does what the operator commanders it that is to say what the operator thinks of is what the instrument does and that's why the English say that a lazy man(operator) blames his tools(instrument)
We can assume that all<span> gravitational potential energy is converted into
kinetic energy of the object.</span><span>
<span>Hence, </span>GPE = KE
Where GPE is gravitational Potential Energy (J)
and KE is Kinetic Energy (J)
GPE = mgh
<span>Where, m is the mass of the object (kg), g is acceleration due to gravity (9.8 m s</span></span>⁻<span>²) and h is the height to the<span> object from ground (m).</span></span><span>
m = 0.18 kg
g = 9.8 m s</span>⁻²<span>
h = 45 m
Hence,
GPE = 0.18 kg x 9.8 m s</span>⁻² x 45 m<span>
= 79.38 J
≈ 79 J
<span>Hence, </span>KE = GPE = 79 J
<span>Hence, the
answer is '79 joules'.</span></span>
