Advantages of using tidal energy:
-Environment-friendly
-A highly predictable energy source
-High energy density
-Operational and maintenance costs are low
-An inexhaustible source of energy
Disadvantages of using tidal energy:
-High tidal power plant construction costs.
-Negative influence on marine life forms.
-Location limits.
-The variable intensity of sea waves.
Bone age : 22,920 years
<h3>Further explanation</h3>
Given
Nt = 2.5 g C-14
No = 40 g
half-life = 5730 years
Required
time of decay
Solution
General formulas used in decay:
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Input the value :
Answer:
c a reaction that requires energy
Explanation:
because it's moving kind of like a human is being more spontaneous by running and or movement it just sounds spontaneous if you think about energy and if you think about the way it works or away human being moved it's hard to explain but it just makes sense why would it be because it's more ordered that one is definitely the one that don't make sense I just don't think it has nothing to do with what it's trying to ask you this answer just makes sense and has a better understanding
