How far apart are two conducting plates that have an electric field strength of 4. 4 kv/m between them, if their potential diffe
IRINA_888 [86]

Conducting plates will be 3.75 m apart if an electric field strength of 4. 4 kV/m between them, if their potential difference is 15 kV

The potential difference, also referred to as voltage difference between two given points is the work in joules required to move one coulomb of charge from one point to the other. The SI unit of voltage is the volt. Volt Formula.

In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.

E = V/d

E = Electric field strength

d = distance between the plates

V = potential difference

Electric field strength = 4 kV/m

Potential difference  =  15 kV

d = V / E =  15 kV / 4 kV/m

  = 3.75 m

Your own car has a mass of 2000 kg. If your car produces a force of 5000 N, how fast will it accelerate?
Sidana [21]

Answer:

2.5m/s²

Explanation:

Given parameters:

Mass of car  = 2000kg

Force produced by the car  = 5000N

Unknown:

Acceleration of the car  = ?

Solution:

According to Newton's second law of motion, Force is a product of mass and acceleration.

  Force  = mass x acceleration

Now, insert the parameters and find the unknown;

  5000 = 2000 x acceleration

   Acceleration  = \frac{5000}{2000}   = 2.5m/s²

In a series RLC ac circuit, a second resistor is connected in series with the resistor previously in the circuit. As a result of
AnnyKZ [126]

Answer:

* The first thing we observe is that the frequency response does not change

* The current that circulates in the circuit decreases due to the new resistance at the resonance point,

          Z = R + R₂

Explanation:

The impedance of a series circuit is

          Z₀² = R² + (X_L-X_C) ²

when we place another resistor in series the initial resistance impedance changes to

          Z² = (R + R₂) ² + (X_L - X_C) ²

           

let's analyze this expression

* The first thing we observe is that the frequency response does not change

* The current that circulates in the circuit decreases due to the new resistance at the resonance point,

          Z = R + R₂

Which energy transformations BEST illustrates why people can walk? A) Chemical energy is being converted into light energy. B) C
Gekata [30.6K]

The answer is letter c.

The explanation behind this is when human consumes a plant or when a human being eats an animal that ate a plant. The chemical energy kept in the plant (or animal) cells is progressed into the cells of the human's body. All of the body progressions, like ingestion, breathing, pumping blood, are driven by cells changing the kept chemical energy into heat and work, in a procedure called respiration. In the muscle cells of the human (or any animal), the chemical energy is converted into mechanical work and heat. The muscle pacts, the legs thrust, and the body jumps into the air.
