Give one example of a thermodynamic cycle that does not account for the carnot efficiency.
Arturiano [62]

Thermo-Electrochemical converter (UTEC) is a thermodynamic cycle that does not account for the Carnot Efficiency.

The Carnot cycle is a hypothetical cycle that takes no account of entropy generation. It is assumed that the heat source and heat sink have perfect heat transfer. The working fluid also remains in the same phase, as opposed to the Rankine cycle, in which the fluid changes phase. A practical thermodynamic cycle, such as the Rankine cycle, would achieve at most 50% of the Carnot cycle efficiency under similar heat source and heat sink temperatures.

<h3>What is Thermo-Electrochemical converter?</h3>

In a two-cell structure, a thermo-electrochemical converter converts potential energy difference during hydrogen oxidation and reduction to heat energy.

It employs the Ericsson cycle, which is less efficient than the Carnot cycle. In a closed system, it converts heat to electrical energy. There are no external input or output devices.

This means there will be no mechanical work to be done, as well as no exhaust. As a result, Carnot efficiency is not taken into account in this cycle. Carnot efficiency is accounted for by other options such as turbine and engine.

Two one-coulomb point charges are at a distance of 1.67 m from each other. What is the size of the electric force between the tw
pychu [463]

Explanation:

The given data is as follows.

       distance (r) = 1.67 m

     q_{1} = q_{2} = 1 C

It is known that formula for electric force between two charges is as follows.

          F = \frac{kq_{1} \times q_{2}}{r^{2}}

Hence, putting the given values into the above formula as follows.

       \frac{9 \times 10^{9} \times 1 \times 1}{(1.67)^{2}}

            = 3.227 \times 10^{9}

As it is given that mass of  Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.

       weight of 1 falcon rocket = 142 \times 10^{3} \times 9.8

Therefore, number of falcon rockets will be calculated as follows.

         No. of falcon rockets = \frac{3.227 \times 10^{9}}{142000 \times 9.8}

                              = 2.31897 \times 10^{3}

                              = 2318.9 falcons

Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.
