Answer:
c. streak
Explanation:
Pyrite is a mineral that looks like gold but actually is iron disulfide.
Pyrite and gold have comparable luster.
Pyrite and gold have different tones of yellow. This can be determined by their streak. Streak is the powdered form of a mineral. A streak of mineral can be found just by rubbing the mineral on a rough surface and comparing the colors.
Pyrite is diamagnetic which is not a strong form of magnetism. Gold is also diamagnetic
Explanation:
the object with the higher temperature has greater thermal energy
So the answer is
the stick of butter with less thermal energy.

Answer:
Gay-Lussac’s law, because as the pressure increases, the temperature increases
Explanation:
First of all, we can notice that the volume of the tank is fixed: this means that the volume of the air inside is also fixed.
This means that in this situation we can apply Gay-Lussac's law, which states that:
"for a gas kept at constant volume, the pressure of the gas is proportional to the absolute temperature of the gas".
Mathematically:
where p is the pressure in Pascal and T is the temperature in Kelvin.
In this case, the tank is filled with air: this means that the pressure of the gas inside the tank increases. And therefore, according to Gay-Lussac's law, the temperature will increase proportionally, and this explains why the tank gets hot.
Answer:
In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough.
In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
