Please re-explain the following phrases in terms of momentum
zheka24 [161]
A. An object in motion will remain in motion unless acted upon by an outside force : The momentum of an object is constant unless an outside force acts on the object.

B. Force is defined as mass times acceleration : the rate of change of the momentum of a particle is proportional to the force F acting on it, hence the force is equal to <span>mass times acceleration.

C. </span>For every action there is an equal and opposite reaction : <span>to every action force there is an equal and opposite reaction force. </span>

Agatha has 1kg samples of two substance- A and B. Substance A has a higher specific heat capacity than substance B. Both samples
Sav [38]

Answer:

Substance A will release more heat.

Explanation:

Let suppose that both substances experiment an entirely sensible heat process and are incompressible and begin at the same temperature. Physically speaking, specific heat (c), measured in kilojoules per kilogram-degree Celsius, can be described by following expression:  

c = \frac{Q}{m\cdot (T_{f}-T_{o})} (1)

Where:

Q - Released heat, measured in kilojoules.

m - Sample mass, measured in kilograms.

T_{o}, T_{f} - Initial and final temperatures of the sample, measured in degrees Celsius.

If we know that c_{A}> c_{B}, m_{A} = m_{B}, T_{A,o} = T_{B,o} and T_{A,f} = T_{B,f}, then we have the following inequation:

\frac{Q_{A}}{m\cdot (T_{A,f}-T_{A,o})} > \frac{Q_{B}}{m\cdot (T_{B,f}-T_{B,o})}

Q_{A} > Q_{B}

Substance A will release more heat.
