A parallel-plate capacitor with circular plates of radius 0.10 m is being discharged. A circular loop of radius 0.20 m is concen

Sedaia [141]

Answer:

7.1934 x 10^12 V/m.s

Explanation:

In order to do this exercise, you need to use the correct formula. Besides that, we need to identify our data.

First we have the radius of the plates which are circular, and it's 0.1 m. The current of the loop (I) is 2.0 A, and the radius of the loop is 0.2 m.

Now with this data, we use the next formula:

I = dE/dt Eo A

Where:

dE/dt = rate of electric field

Eo = constant of permittivity of free space

A = Area of circle

Solving for dE/dT:

dE/dt = I / Eo*A

Now, the area of the circle is A = πr²

A = 3.1416 * (0.1)² = 0.031416 m²

Now solving the electric field:

dE/dt = 2 / (8.85x10^-12 * 0.031416)

dE/dt = 7.1934 x 10^12 V/m.s

Rooted plants are most likely found in which aquatic zone?

Mnenie [13.5K]

Ans. Littoral zone.

Littoral zone can be defined as the area of a rive, sea, or lake, which lies close to the shore. It is characterized by abundant sunlight, dissolved oxygen, nutrients, and high water motion. These characteristics make it suitable for marine life. Hence, littoral zone is enriched with various plants and animal species, and coral reefs.
