Answer:
B. it increases
Explanation:
Remember that momentum = mass * velocity. So momentum and velocity are directly proportional, so as velocity increases, so will momentum of the object.
Cube A has more thermal energy than cube B.
Explanation:
It is obvious that cube A has gained more thermal energy compared to cube B.
From the description of the experiment, both cubes had the same temperature which is 50°C. Temperature is the degree of hotness or coldness of a body.
Thermal energy is a form of energy expressed as heat in a body.
Cube A has a higher volume because it has gained more thermal energy than Cube B.
Thermal energy increases the rate of vibration of atoms in the crystal lattice of the solid. The more the thermal energy, the more the vibration. This is why Cube A has expanded so much and changed volume.

Answer:
0
Explanation:
The overall charge on this atom is 0.
To find the charge on an atom;
charge = number of protons - number of electrons.
Note:
- Protons are the positively charged particles in an atom
- Electrons are the negatively charged particles in an atom
- Neutrons carries no charges on them.
Since the atom is made up of equal number of protons and electrons, the charge on it is 0.
If the number of electrons is more, the atom will be negatively charge but if the number of protons is more, it will be positively charged.
