100N divide 2 by 200 it is 100
The largest reservoir of the Earth's carbon is located in the deep-ocean, with 36,000 billion tons of carbon stored, whereas approximately 65,500 billion tons are found on Earth combined.
This is by far the largest reservoir, carbon dioxide is stored in the interior of the earth in the form of carbonate rocks, such as limestone, dolomites, and chalk.
Answer: C) the energy gained by an electron in moving through a potential difference of 1 volt
Explanation: In order to explain this response we have to consider that the potential energy for any charge is given by:
Up=q*ΔV then if we consider an electron accelerate by a difference potential of 1V, we have:
Up=e*V ( energy UNITS, which is equal to 1.6*10^-19 J).
The option A) and B) are wrong because elentron Volt has units of energy not force.
The option D) is also wrong because the the work done to move un electron one meter also depends of the magnitud of the potential difference ( electric field) where the electron is moving .
Finally the option D) is false because the one C*V is one J, is huge quantity of energy compared to the electron Volt (eV).
Answer:
endothermic reactions
Explanation:
An instant cold pack is a device that consists of two bags; one containing water, inside a bag containing ammonium nitrate, calcium ammonium nitrate or urea. When the inner bag of water is broken by squeezing the package, it dissolves the solid in an endothermic reaction.
