Healthy to get better at your daily activities but harmful to your body if you overdo it
Answer:
The value of Q is - 8 C
Explanation:
Given;
the magnitude of first charge = 2 C
position of the first charge = 0
_ (2m) 0(+2C) +(2m)(Q)
------------------------------------------------------------------------------------
E₁ --------------------------------->
<------------------------------------------------------------------ E₂
E₁ and E₂ are equal in magnitude but opposite in direction
| E₂ | = | E₁ |

Thus, since E₂ is opposite in direction to E₁, the Q = - 8 C

-Energy Is The Ability To Do Work-
Energy comes into different forms but they can all be placed in two different categories. These categories are "potential" which means stored energy and energy of position and "kinetic" which is the energy of motion.
POTENTIAL ENERGY <em>Stored energy and the energy of position</em>
CHEMICAL ENERGY <em>Energy in the bonds of atoms and molecules</em>
MECHANICAL ENERGY <em>Energy stored in objects by tension</em>
NUCLEAR ENERGY <em>Energy stored in the nucleus of an atom</em>
GRAVITATIONAL <em>Energy that is stored in an object's height</em>
ELECTRICAL ENERGY <em>Delivered by tiny charged particles called electrons</em>
KINETIC ENERY <em>The energy of motion</em>
THERMAL ENERGY <em>The vibration and movement of atoms and molecules in substances.</em>
RADIANT ENERGY<em> </em><em>Electromagnetic energy that travels in waves</em>
Greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up. Using fossil fuels results in a rise of greenhouse gases.
The density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.
<h3>What is the relationship between acceleration and density?</h3>
For a solid falling through a viscous fluid, the acceleration of the object decreases until it attains terminal velocity.
The acceleration of the body increases with increase in density of the solid.
When density of solid = density of liquid, acceleration a = g
When density of solid = 2 × density of the liquid, acceleration a = g/2.
Therefore, the density of the metal is twice the density of liquid since acceleration, a is half of accelerating due to gravity, g.
