c. condensation
They are opposite processes that involve the same transfer of energy
You can thank me if this answer helps. The energy coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests,even before dinosaurs!
Answer:
a
b
Explanation:
From the question we are told that
The spring constant is
The mass of the block is
Considering question a
Generally the weight of the block is mathematically represented as
=>
=>
Generally the force exerted on the spring is mathematically represented as
At equilibrium
=>
=>
=>
Considering question b
Generally the energy stored in the spring is mathematically represented as
Now the potential energy of the block before it is drooped is mathematically represented as
Generally from the law of energy conservation we have that
=>
=>
=>
