What are the charges and masses of particles?

 The charges and masses of the fundamental particles are as follows:

  • Electron: charge = -1.602176634 x 10^-19 coulombs, mass = 9.10938356 x 10^-31 kilograms
  • Proton: charge = 1.602176634 x 10^-19 coulombs, mass = 1.672621898 x 10^-27 kilograms
  • Neutron: charge = 0 coulombs, mass = 1.674927471 x 10^-27 kilograms
  • Positron: charge = 1.602176634 x 10^-19 coulombs, mass = 9.10938356 x 10^-31 kilograms

Note that the positron has the same charge as the electron but has opposite charge. The electron and the positron are known as leptons, while protons and neutrons are known as baryons.

What is a para-substituted phenol?

  A para-substituted phenol is a phenol molecule in which one or more substituent groups are attached to the para position of the phenol ring. The para position is the location on the phenol ring that is directly across from the hydroxyl (OH) group. In other words, the substituent groups are located at the fourth and fifth positions on the phenol ring. These substituents can be any type of chemical group, such as alkyl, halogen, or nitrile groups, and they can affect the properties and reactivity of the phenol molecule .

Why are the automobile companies stopping diesel vehicles?

                      There are a few reasons why automobile companies are phasing out diesel vehicles. 1.Environmental regulations: Many countries have enacted stricter emissions standards for diesel vehicles, which can be more difficult and costly for manufacturers to comply with. 2.Consumer preference: Increasingly, consumers are turning away from diesel vehicles in favor of hybrids and electric vehicles, which are perceived to be more environmentally friendly. 3.Health concerns: Diesel exhaust fumes contain harmful pollutants such as nitrogen oxides (NOx) and particulate matter (PM) that can have detrimental effects on human health. 4.Government incentives: some governments are offering incentives for the purchase of electric vehicles or imposing penalties on the registration of diesel vehicles, which can make it less attractive for the manufacturers to produce them. 5.More efficient and cheaper alternatives: Electric vehicles are becoming more efficient an
