Answer:
Conservation of energy
Explanation:
The first law of thermodynamics is given by :
Here,
Q is amount of heat added to the system
is change in internal energy
W is amount of work done by the system
It is clear that the energy can be neither created nor destroyed, it remains conserved. Hence, first law of thermodynamics shows that conservation of energy.
Answer:
The period is
Explanation:
From the question we are told that
The mass is
The extension of the spring is
The spring constant for this is mathematically represented as
Where F is the force on the spring which is mathematically evaluated as
So
The period of oscillation is mathematically evaluated as
substituting values
