FinnZ [79.3K]

Answer:

Explanation:

If a car is moving to the left with constant velocity, one can conclude that

there must be no forces applied to the car .  The net force applied to the car is zero.

Since there is no acceleration ,no net force is applied , hence no force acts on the car.

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.
