Answer:Thermal energy is a measure of a substance 's specific heat
Explanation:
Incompressible. Compressibility is determine by the amount of space between particles in each state.
The acceleration of the box is approximately 
Explanation:
According to Newton's second law of motion, the net force acting on the box is equal to the product between its mass and its acceleration:

where
is the net force
m = 12.0 kg is the mass of the box
a is the acceleration
The net force can be written as

where
is the applied forward force
is the friction force
Combining the two equations,

And solving for the acceleration,
