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.

You name binary ionic compounds by naming the first element or the ___ first,
Nuetrik [128]

Answer:

cation, anion

Explanation:

Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)

example:

NaCl

Na^+1

Cl^-1

Sodium Chloride

What is the resistance force when you walk up an inclined plane?<br> Please help quick!
Dominik [7]
Friction
Friction also affects the movement of an object on a slope. Friction is a force that offers resistance to movement when one object is in contact with another. Imagine now that you were on the downside of the object and applying force to keep the object in the same place (not moving)

(sorry if this is late)

Explanation:

Rest of the answers.

As solar wind approaches Earth, what happens to the charged electrons?

They are deflected as Earth’s magnetic field exerts force on them.

Which statement is accurate about how the aurora borealis is formed?

When the electrons fall to a lower energy state, they release energy as electromagnetic radiation, light.

How does the energy in the light of the aurora borealis compare to the energy as an excited electron returns to its original energy level?

equal to

During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?

First, the electron absorbs energy to move to a higher energy level.
