Answer:

Electric flux \phi=31562.63\ Nm^2/C

Explanation:

Given that,

Electric field acting on the circular area, E=(4000j+3000k)\ N/C

We need to find the electric flux through a circular area of radius 1.83 m that lies in the xy-plane. It lies in xy plane, such that the area vector point in z direction. The electric flux is given by :

\phi=E{\cdot}A

\phi=(4000j+3000k){\cdot}Ak

Using dot product properties, we get the value of electric flux as :

\phi=3000\times Ak

\phi=3000\times \pi (1.83)^2

\phi=31562.63\ Nm^2/C

So, the electric flux through a circular area is \phi=31562.63\ Nm^2/C . Hence, this is the required solution.

If little herbert does something unconsciously he will probably, he's definitely very unware of he has done

Doing something unconscious may have some implications which may not be favourable.

<h3>What is unconscious?</h3>

Unconscious simply means a state of someone being absent minded of what is happening to him or her at a particular period of time

So therefore, if little herbert does something unconsciously he will probably, he's definitely very unware of he has done

sergey [27]

Answer:P:Increase Q:Decrease

Explanation: The price of the product will increase as the imposed per-unit excise tax on the sale of the good. This is true for both Perfectly-elastic and relatively elastic products.

The quantity demanded of the product will decrease as the price of the product increases, this his is true for both Perfectly-elastic and relatively elastic products. It will follow the law of Demand and Supply.
