Answer:

Nuclear reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide during operation. However, processes for mining and refining uranium ore and the production of reactor fuel all require a large amount of energy. Nuclear plants create more jobs than other forms of energy. 7 They create 0.5 jobs for every megawatt hour of electricity produced. This is in comparison to 0.19 jobs in coal, 0.05 jobs in gas-fired plants, and 0.05 in wind power. As a result, new gas-fired power plants were built from 1992 to 2005. an Advantages of nuclear energy Low-cost energy. Although building nuclear power plants has a high initial cost, it's relatively cheap to produce energy from them and they have low operating cost.

brilliants [131]

Based on a scene showing a physical change in a piston-cylinder assembly, the thermodynamic numbers indicated below are 760 torr 760.

<h3>What elements make up the first rule of thermodynamics?</h3>

The first law of thermodynamics states that the following equation describes how the change in internal energy relates to the heat exchanged by the system and the work performed on or by the system: U = Q + W, where Q represents the heat energy that the system exchanged.

<h3>What are the thermodynamic quantities' two components?</h3>

Extensive and intensive thermodynamic quantities are traditionally separated into these two categories. While intensive quantities are independent of system size, extensive quantities grow linearly with system size.

Which list BEST identifies how the arrows should be arranged around the paper leaf in the model to represent the movement of mat

Andrew [12]

Answer:

D. Point into Leaf: water(H₂O), carbon dioxide (CO₂) sunlight, Point away from leaf: Sugars, oxygen (O₂)

Explanation:

Photosynthesis is the process used in the production of chemical energy in the form of energy containing organic compounds and oxygen from atmospheric carbon dioxide and liquid water enabled with the energy captured from light (mainly Sunlight) by the chlorophyll in green plants and other organisms

The basic chemical reaction involved in a photosynthesis reaction is presented as follows;
