Ice Wedging and Plant Growth
Answer:
Explanation:
The three main particles that make an atom are:
- Proton: its mass is , it carries an electric charge of +e (
), and it is located in the nucles of the atom
- Neutron: its mass is 
, it carries no electric charge, and it is also located in the nucleus of the atom
- Electron: its mass is 
, it carries an electric charge of -e (), and it is located outside the nucleus
Answer and Explanation:
Polar molecules are formed as a result of unequal sharing of electrons by the atoms in the molecule which creates polarization like that in water molecule.
If the electrons are shared equally by the atoms in the molecule then there won't be any polarization of the molecule and the molecule is non polar.
Electro-negativity is that property of an atom which lets it attract negative charges, i.e., electrons. The more the electro-negativity of an atom in the molecule the more are the chances of its polarization.
Answer:
The coefficient is 0.90
Explanation:
Drawing a diagram makes thing easier, we will assume that the acceleration tends to zero because it start barely moving.
