Answer:
<h2>Potential difference across capacitors in parallel
</h2>
Two or more capacitors are said to be connected in parallel if each one of them is connected across the same two points. In a parallel combination of capacitors potential difference across each capacitor is same but each capacitor will store different charge.
If the force applied(Fa) is pushing down to chair friction goes up. if Fa pushing up, friction goes down. if Fa pushing sideways and the chair stays stationary, friction stay the same. if Fa push sideway and chair moves, friction goes down
Answer:
1)
2)
Explanation:
1)
The intensity equation is given by:
Where:
- P is the power of the radio wave
- r is the distance from the source
2)
Now, the intensity and the electric field are related as:
Here:
- c is the speed of light
- ε₀ is the electric permittivity
- E is the electric field
We need to solve it for E.

An externality, sometimes called a spillover, occurs when an exchange between a buyer and seller has an impact on a third party who is not part of the exchange. Externalities can be positive or negative
<h3>What are Externalities?</h3>
Externalities refers to situations when the effect of production or consumption of goods and services imposes costs or benefits on others which are not reflected in the prices charged for the goods and services being provided.
Externalities Private markets offer an efficient way to put buyers and sellers together and determine what goods are produced, how they are produced, and who gets them. The principle that voluntary exchange benefits both buyers and sellers is a fundamental building block of the economic way of thinking. But what happens when a voluntary exchange affects a third party who is neither the buyer nor the seller?
Externalities can be negative or positive. If you hate country music, then having it waft into your house every night would be a negative externality. If you love country music, then what amounts to a series of free concerts would be a positive externality.

Explanation:
Correct equation is
C + O2 -> CO2
Carbon react with Oxygen to form carbon dioxide
This is a combustion reaction
