This is somewhat of a misleading question, because all of these elements are necessary to convert motion into electricity at some point, but the generator is the last in line.

Determine the total distance
This is calculated by summing up the distance in each segment.
Answer:
LIBs have had a huge impact on our society. They enabled modern portable electronics such as laptops and mobile phones. And they are now enabling clean and low-carbon transport, be it via electric cars or even flying taxis, and grid-scale storage of renewable energy
Explanation:
Explanation:
1. subatomic particles.
2.proton, electron and neutron
3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element
4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms
5. Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg
7.The center of the atom is called a nucleus
8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.
9. A charged particle is also called an ion
Remember:
6.022×10²³ molecules = 1 mol (Avogadro's number)
NH₃ = ammonia
To get molar mass of NH₃, add the mass of nitrogen + 3 times the mass of hydrogen (because there are 3 hydrogens in NH₃).
14.01 + 3(1.01) = 17.04 grams NH₃ = molar mass
1) Set up your equation. You want to cancel out molecules, and get to grams through moles.
So multiply 3.4×10²⁴ molecules of ammonia × 1 mol of ammonia × 17.04 grams of ammonia and divide it by 6.022×10²³ molecules of ammonia and 1 mol of ammonia.
3.4×10²⁴ molecules of ammonia × 1 mol of ammonia × 17.04 grams of ammonia
6.022×10²³ molecules of ammonia 1 mol of ammonia
Your answer should come out to be: 96.20724 grams of ammonia
Round to 2 sig figs: 96 grams of ammonia
