Answer:
The last answer would be correct because if you have ever done it before you would know that rubbing your feet (just like the rubbing of ice crystals) on the carpet will create the energy you need, then once you touch the metal it creates that spark!
Explanation:
hoped that helped-I would be thankful for brainliest ;)
Radiant energy is converted to electrical energy, when a solar panel uses sunlight to provide power to a house.
<h3>
What is electrical energy?</h3>
- Electrical energy is produced when electrically charged particles move, producing energy.
- Electrical energy is a general term that describes energy that has been transformed from electric potential energy.
- Electric current and electric potential given by an electrical circuit serve as the source of this energy (e.g., provided by an electric power utility).
- This electric potential energy stops being electric potential energy after it has been changed into another form of energy.
- Because of this, all electrical energy is potential energy before it is used.
- Electrical energy can always be referred to as another type of energy once it has been transformed from potential energy (heat, light, motion, etc.).

<span>Answer:
A 1.00 L solution containing 3.00x10^-4 M Cu(NO3)2 and 2.40x10^-3 M ethylenediamine (en).
contains
0.000300 moles of Cu(NO3)2 and 0.00240 moles of ethylenediamine
by the formula Cu(en)2^2+
0.000300 moles of Cu(NO3)2 reacts with twice as many moles of en = 0.000600 mol of en
so, 0.00240 moles of ethylenediamine - 0.000600 mol of en reacted = 0.00180 mol en remains
by the formula Cu(en)2^2+
0.000300 moles of Cu(NO3)2 reacts to form an equal 0.000300 moles of Cu(en)2^2+
Kf for Cu(en)2^2+ is 1x10^20.
so
1 Cu+2 & 2 en --> Cu(en)2^2+
Kf = [Cu(en)2^2+] / [Cu+2] [en]^2
1x10^20. = [0.000300] / [Cu+2] [0.00180 ]^2
[Cu+2] = [0.000300] / (1x10^20) (3.24 e-6)
Cu+2 = 9.26 e-19 Molar
since your Kf has only 1 sig fig, you might be expected to round that off to 9 X 10^-19 Molar Cu+2</span>

Answer:
Buoyancy.
Explanation:
Buoyancy is a force created by the water that is displaced by an object. It is directly proportional to the amount of water that is being displaced by an object.
Hence, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
<em>The unit of measurement for the buoyancy of an object is Newton (N).</em>
