The electric potential difference is the electric potential energy per unit charge
Explanation:
First of all, we define the concept of electric potential. The electric potential is a measure of the gradient of the electric field at a certain point of the space. The electric potential at a distance from a positive charge of magnitude is given by
where k is the Coulomb's constant.
Now we can define the electric potential energy and the electric potential difference:
The electric potential energy is also defined as the work done on a charge q moved through a potential difference of . Consequently, the potential difference represents the work per unit charge done, i.e. the work done when moving a unitary charge through a potential difference .

Answer:
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by a combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.
Explanation:
Answer:
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

Answer: 54 miles in 1hr 30min
Explanation:
The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes
