Answer:
Since opposite charges attract each other, the negatively charged electrons are attracted to the positively charged protons. ... Together, all of the electrons of an atom create a negative chargethat balances the positive charge of the protons in the atomic nucleus.
Explanation:
Answer:
Explanation:
The formula for the potential energy of a dipole placed in an electric field is given by
U = - pE Cos θ
where, θ is the angle between dipole moment and the electric field vector.
For θ = 0°,
initial potential energy, Ui = - pE
For θ = 180°,
final potential energy, Uf = - pE Cos 180 = pE
Change in potential energy
ΔU = Uf - Ui
ΔU = pE - (-pE)
ΔU = 2pE
Answer:
1. Both are respiratory organs found in vertebrates.
2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.
3. Respiratory membranes present in both make the exchange of gases easier.
4. Blood vessels found around them enable the breathing process.
Explanation:
Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.
The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.
Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.
Answer:
10,000 eV
Explanation:
Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:
where
q is the electron charge
is the potential difference
Here we have:
is the electron's charged
is the potential difference
Substituting into the formula, we have
