The statement '<span>The more particles a substance has at a given temperature, the more thermal energy it has' is true. </span><span>The
kinetic molecular theory of gases has three main laws and one of them is the
average kinetic energy of the particles in a gas. The average kinetic energy of
the gas particles is the behavior and movement it does in the surroundings. It
is directly proportional to temperature wherein if you increase the
temperature, the kinetic energy of a particle also increases. It will also
decrease its movement or its kinetic energy if the temperature lowers. </span>
D.) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case.
If an object changes direction while travelling will an object's displacement and distance travelled be different.
Some people believe that distance and displacement are simply different names for the same quantity. However, distance and displacement are not the same thing. If an object changes direction while travelling, the total distance travelled is greater than the displacement between those two points.
The magnitude of the displacement is always less than or equal to the distance because it is measured along the shortest path between two points.
When the direction of displacement does not change, the magnitude of the displacement and distance are the same. When a body travels in a straight line, for example, its displacement and distance are the same.

Answer:
The value of charge q₃ is 40.46 μC.
Explanation:
Given that.
Magnitude of net force
Suppose a point charge q₁ = -3 μC is located at the origin of a co-ordinate system. Another point charge q₂ = 7.7 μC is located along the x-axis at a distance x₂ = 8.2 cm from q₁. Charge q₂ is displaced a distance y₂ = 3.1 cm in the positive y-direction.
We need to calculate the distance
Using Pythagorean theorem
Put the value into the formula
We need to calculate the magnitude of the charge q₃
Using formula of net force
Put the value into the formula
Hence, The value of charge q₃ is 40.46 μC.
