Electric Charge
Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge (commonly carried by protons and electrons respectively). Unlike charges attract one another while like charges repel one another. Neutral refers to an object that carries no net charge. Classical electrodynamics, the name given to an early understanding of how charged particles interact, is still accurate for issues that do not call for taking into account quantum phenomena.
The coulomb (C), which bears the name of French physicist Charles-Augustin de Coulomb, is the SI-derived unit of electric charge. The charge symbol, lowercase q, is frequently used.

Answer:

Explanation:
Let assume that air behaves ideally. The equation of state of ideal gases is:

Where:
- Pressure, in kPa.
- Volume, in m³.
- Quantity of moles, in kmol.
- Ideal gas constant, in
.
- Temperature, in K.
Since there is no changes in pressure or the quantity of moles, the following relationship between initial and final volumes and temperatures is built:

The final temperature is:



Convection is the circular motion that occurs as hotter air or liquid increases when the cooler air or liquid drops down, and has faster moving molecules, rendering it less dense. Convection currents within the earth shift layers of magma, and currents are formed by convection in the ocean.
Its b i belive
because it the only thing i saw on the list that conduts
The correct answer is a blackhole.
A blackhole is the only object in which nothing, not even light can escape.
Hope this helps!
