My answer -

Electrical pressure, called "electro-motive force" (EMF), is what causes current <span>to flow in an electrical circuit. EMF is measured in volts. Pressure and the </span><span>quantity of electricity transmitted can be considered analogous to pressure and </span><span>quantity of water flowing in pipes: the longer the distance, the higher is the </span><span>flow of water (called the "flow of electrical charge, which is also known as the </span><span>"electric current"). That is why, for long distance transmission, high pressure </span><span>(voltage for electricity) is required, failing which, the current - and </span><span>therefore the power - will not reach the intended destination. Instead, it will </span><span>be lost (also called "dissipate") along the way. We can think of electrical
 </span><span>current as the quantity of electricity which will be drawn from the pipeline
</span><span> cables for electricity) at the pressure (= voltage) required. </span>


P.S

Happy to help you have an AWESOME!!! day ^-^

If an automobile engine delivers 42.0 hp of power, how much time will it take for the engine to do 6.20 â 105 j of work? (hint:
Elena L [17]
To be able to answer this item, we are to calculate the power that the machine could deliver from hp to kW. 

      (45 hp)(746 W/1 hp) = 33570 W

Power is the amount of energy delivered at a certain period. 

             t = (6.20 x 10^2 J)/ (33570 kJ/s)

             t = 0.01845 s

Citrus2011 [14]

A galvanic cell is formed when two metals are immersed in solu- tions differing in concentration 1 when two different metals are immersed.

<h3>What is galvanic cell?</h3>
  • The galvanic cell utilizes the ability to split the flow of electrons in the process of oxidization and reduction, compelling a half-reaction and connecting each with a wire so that a way can be formed for the flow of electrons via such wire.
  • A galvanic cell is an electrochemical cell that transforms the chemical energy of a spontaneous redox response into electrical energy. It has an electrical possibility equal to 1.1 V. In galvanic cells, oxidation occurs at the anode and it is a negative plate. Lessening occurs at the cathode and it is a positive plate.
  • A galvanic cell is an electrochemical cell that converts the free liveliness of a chemical method into electrical energy. A photogalvanic cell generates species photochemically which react resulting in an electrical current via an external circuit.

If you have 12 atoms of hydrogen before a chemical reaction how many atoms of hydrogen will be president after the chemical reac
kaheart [24]
If you have 12 atoms of hydrogen before a chemical reaction, the number of hydrogen atoms that will be present after the chemical reaction is 12 atoms.
The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed before and after any chemical reaction.
According to the Law of Conservation of Mass (LOCOM), a balanced chemical equation requires that the number of atoms on the reactant side must be equal to the number of atoms on the product side of any chemical reaction.
In this context, a chemical reaction having 12 atoms of hydrogen as reactants at the beginning, should also produce a total of 12 atoms of hydrogen as products at the end of the chemical reaction.

Dimensional Analysis : 3 days to seconds
LuckyWell [14K]
Hi,

To convert 3 days to seconds write this.

1h = 3600s
24h = 3600 · 24 = 86400
3 days = 3 · 86400 = 259200sec

Hope this helps.
