1) First of all, let's calculate the potential difference between the initial point (infinite) and the final point (d=0.529x10-10 m) of the electron.
This is given by:

Where E is the electric field generated by the proton, which is
where

is the Coulomb constant and

is the proton charge.
Replacing the electric field formula inside the integral, we obtain

2) Then, we can calculate the work done by the electric field to move the electron (charge

) through this

. The work is given by
Ammonium chloride is soluble at 80g.
The correct answer for the question that is being presented above is this one: "<span>c. Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun."</span>
Here are the following choices:
a. Planets orbit in elliptical patterns; the bigger the planet, the more gravitational pull; a planet's gravitational pull is stronger or weaker depending on its distance from the Sun.
b. A planet's orbit covers equal distances in equal amounts of time; the speed of a planet's orbit depends on its distance from the Sun; the bigger the planet, the slower it moves.
c. Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun.
Answer: Yes
Explanation: A molecule has a bond dipole but not have a molecular dipole.
Dipole moment: dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.
Example:
lets take an example of
molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.
due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.
Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.
Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.
