It's false because in some countries it's used to make power.

Answer:

FALSE

Explanation:

Geothermal energy can be use to form electricity like other sources of energy.

In this case of geothermal energy first of all steam is produced with the help of thermal energy recovered by the geothermal energy. This steam is taken to high pressure which is used to operate the turbine.

Now this turbine will convert the mechanical energy received by steam into electrical energy.

So here this type of energy sources are used in several countries for the electricity production

A circuit supplied with 110V carries 5 Amps current. Calculate the Resistance value of the circuit?
IgorC [24]

Answer:

The value is R =  22 \  \Omega

Explanation:

From the question we are told that

     The voltage is  V  =  110 \  V

    The current is  I  =  5 \  A

Generally the resistance value is mathematically represented as

         R =  \frac{V}{I}

=>      R =  \frac{110}{5}

=>      R =  22 \  \Omega

Answer:

A. U_0 = \dfrac{\epsilon_0 A V^2}{2d}

B. U_1 = \dfrac{\epsilon_0 A V^2}{6d}

C. U_2 = \dfrac{K\epsilon_0 A V^2}{2d}

Explanation:

The capacitance of a capacitor is its ability to store charges. For parallel-plate capacitors, this ability depends the material between the plates, the common plate area and the plate separation. The relationship is

C=\dfrac{\epsilon A}{d}

C is the capacitance, A is the common plate area, d is the plate separation and \epsilon is the permittivity of the material between the plates.

For air or free space, \epsilon is \epsilon_0 called the permittivity of free space. In general, \epsilon=\epsilon_r \epsilon_0 where \epsilon_r is the relative permittivity or dielectric constant of the material between the plates. It is a factor that determines the strength of the material compared to air. In fact, for air or vacuum, \epsilon_r=1.

The energy stored in a capacitor is the average of the product of its charge and voltage.

U = \dfrac{QV}{2}

Its charge, Q, is related to its capacitance by Q=CV (this is the electrical definition of capacitance, a ratio of the charge to its voltage; the previous formula is the geometric definition). Substituting this in the formula for U,

U = \dfrac{CV^2}{2}

A. Substituting for C in U,

U_0 = \dfrac{\epsilon_0 A V^2}{2d}

B. When the distance is 3d,

U_1 = \dfrac{\epsilon_0 A V^2}{2\times3d}

U_1 = \dfrac{\epsilon_0 A V^2}{6d}

C. When the distance is restored but with a dielectric material of dielectric constant, K, inserted, we have

U_2 = \dfrac{K\epsilon_0 A V^2}{2d}
