Tenacity or Toughness
Answer:
Mass does not change based on gravity
Explanation:
Mass is how much matter is in an object. That's why we have the same mass on Moon, Neptune, etc.
But weight depends on gravity. That's why our weight on the moon is less than Earth because the Moon's gravity is less than Earth.
Power has no effect on regardless of whether the photoelectric impact happens. The deciding property is recurrence and since recurrence and wavelength are conversely corresponding, wavelength matters also. On the off chance that a recurrence of light can't make the photoelectric impact happen, regardless of what the power is, the light can't get it going.
Answer:

Explanation:
Hello there!
In this case, according to the rules for the oxidation states in chemical reactions, it is possible to realize that lone elements have 0 and since magnesium is in group 2A, it forms the cation Mg⁺² as it loses electrons and oxygen is in group 6A so it forms the anion O⁻²; therefore resulting oxidation numbers are:
