<span>The major difference is the presence or absence of external energy source. In an electrolytic cell, one does not need an outside source of energy like a battery while in a voltaic cell the reaction occurs simultaneously, or without help. The other major difference is that in an electrolytic cell, the flow of electrons is from positive(cathode) to negative(anode). In a voltaic cell the flow of electrons is from negative(anode) to positive(cathode).</span>
The receiver of a signal must understand the code or language being used to avoid confusion and losses.
<h3>What is a Signal?</h3>
This is usually in the form of a sound or body movement and is involved in conveying messages to people.
The receiver must understand the code or language in order to prevent confusion or loss of lives and properties.

The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet
Explanation:
We can solve this problem by applying Newton's third law, which states that:
<em>"When an object A exerts a force (called </em><em>action</em><em>) on an object B, then object B exerts an equal and opposite force (called </em><em>reaction</em><em>) on object A"</em>
In this problem, we can identify:
- The sun as object A
- The planet as object B
By applying Newton's third law, we can state that:
- The action is the gravitational force exerted by the sun on the planet
- The reaction is the gravitational force exerted by the planet on the sun
According to the law, the two forces are equal in magnitude and opposite in direction: so, we can conclude that
The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet
