The value of the second charge is 1.2 nC.
<h3>
Electric potential</h3>
The work done in moving the charge from infinity to the given position is calculated as follows;
W = Eq₂
E = W/q₂
<h3>Magnitude of second charge</h3>
The magnitude of the second charge is determined by applying Coulomb's law.

Thus, the value of the second charge is 1.2 nC.

Answer: The correct answer is "radiometric dating".
Explanation:
Radiometric dating: It is a technique which is used to estimate the age of the rocks. In this technique, there is neither daughter product or parent nuclide can leave or enter the material after its formation.
Radioactive atoms are unstable. It decays into stable daughter atom.
Firstly, measure the quantity of the unstable atoms which are left in rock. Then, compare remaining the quantity of the unstable atoms with the quantity of stable daughter atoms in the rock to calculate the passed time since that rock formed.
Therefore, Scientists have been able to estimate the age of our solar system by radiometric dating.
1. A body is in motion when it changes its position at a certain time/duration.
2. Speed is related to how fast a body is moving.
3. Speed means that a body is moving and covering distance at a certain time.
4. Speed<span> is the distance traveled by an object where as, </span>velocity<span> is distance traveled by an object per unit time in a particular direction. </span>
5. Velocity is the rate of change of distance or direction of a body with respect to time.
Answer:
Circle or pie graph is used to show how a part of something relates to the whole.
Explanation:
Pie graphs are easy to read and can present a very clear picture of the relationships.
Answer:
