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.

There are loads of similarities, but there are differences and that's what you want!
Speed- Is usually referring to how fast an object moves, it is calculated by space per unit.
Velocity- Refers to the rate at which said object changes position in a certain direction. Usually calculated by the displacement of space per unit.
SO it sounds the same, but simple answer Velocity deals with direction, and speed does not!
Resolving vectors question. See diagram enclosed.
In phase would mean both waves are at a positive peak, out of phase would mean one is at a positive whilst the other is at a negative. Out of phase would mean the waves cancel each other out
