HCl is a strong electrolyte and when it dissolves in water it separates almost completely into positively - charged hydrogen ions and negatively - charged chloride ions. This aqueous solution is usually called hydrochloric acid.
Explanation:
It is given that,
Electric field experienced by an electron,
Charge on electron,
Mass of electron,
The electric force is balanced by the force acting on electron as,
ma = qE
So, the acceleration of the electron is . As the electron is a negatively charged particle, the field lines is from negative to positive charge.
Answer:
both technicians
Explanation:
parts of a machine that move against themselves need to be lubricated to reduce friction and heating in the system.
since friction causes heating and wearing away of parts, it is important to lubricate them.
engine bearings move against themselves, because the teeth on one moves another
