In an RL series circuit, an inductor of 4.74 H and a resistor of 9.33 Ω are connected to a 26.4 V battery. The switch of the cir

cuit is initially open. Next close the switch and wait for a long time. Eventually the current reaches its equilibrium value. At this time, what is the corresponding energy stored in the inductor? Answer in units of J.

Answer:

The energy is   U =  18.98 \  J

Explanation:

From the question we are told that

   The inductor is  L  =  4.74 \ H

    The resistance of the resistor is R =  9.33 \  \Omega

    The voltage of the battery is V =  26.4 \  V

Generally the current flowing in the circuit is mathematically represented as

      I =  \frac{V}{R}

=>   I =  \frac{26.4}{9.33 }

=>   I =  2.83 \ A

Generally the corresponding energy stored in the circuit is  

       U =  \frac{1}{2} * L  *  I^2

        U =  \frac{1}{2} *  4.74  *  2.83 ^2

       U =  18.98 \  J

Calculate Gravitational Potential Energy for an object on Earth with a mass of 2 kg and a height of 7 m.
victus00 [196]

Answer:

137.2J

Explanation:

Ep= mgh

Given,

  • m=2kg
  • h=7m

and we know, g = 9.81 N/kg

Ep= 2 × 9.81 × 7

Ep= 137.2J

Gauss's Law states that the net electric flux, , through any closed surface is proportional to the charge enclosed: . The analog
Natali [406]

The analogous formula for magnetic fields is the Ampere's law.

To find the answer, we need to know about the Ampere's law of magnetism.

<h3>What's Ampere's law of magnetism?</h3>

Ampere's law states that the close line integral of magnetic field around a current carrying loop is directly proportional to the current enclosed within it.

<h3>What's is the mathematical expression of Ampere's law?</h3>

Mathematically, Ampere's law is

B•dl= μ₀I

Thus, we can conclude that the analogous formula for gauss law is the Ampere's law in magnetism.

What is the main determining factor in defining boundaries between layers of earth's atmosphere?
konstantin123 [22]
The main determining factor in defining boundaries between layers of earth's atmosphere would be temperature changes in these layers. Temperature is one essential property that varies in the atmosphere. Based from this variation, the atmosphere is divided into four major layers and further to three smaller layers -  troposphere, tropopause, the stratosphere,  stratopause, the mesosphere, mesopause, and the thermosphere.The troposphere is the layer that is nearest to the surface of the Earth. It is the part where humans, plants and animals survive. Also, it is the warmest layer of the atmosphere. And as we go higher the atmosphere, the temperature would drop making it much cooler.
