The law of conservation tells us that no mass is lost. This is true because when wood burns or turns into ash, some of it is escaped as gases like carbon dioxide and water vapor into air . If we calculate the mass of these atmospheric gases that evolved when the wood turned into ash, we would find that the total mass of all these substances including the ash is equal to the log of wood.
Answer:
The acceleration of the object is 
.
Explanation:
Given that,
Mass of the block, m = 2.6 kg
Spring constant of the spring, k = 126 N/m
At the instant when the displacement of the spring from its unstained length is 0.115 m. We need to find the acceleration of the object.
When the block is displaced, the force acting on the spring is equal to the force due to its motion. Such as :
a is acceleration of the object
So, the acceleration of the object is .

C. The potential energy would double.
Explanation:
The potential energy of an object is the energy at rest. it is the product of its mass, gravity and height.
Potential energy = mgh
where m is the mass
g is the acceleration due to gravity
h is the height
From the above, potential energy is proportional to the height. If any change in any of the parameters will directly affect the potential energy. This implies that if height is double, the potential energy is doubled.
