70 - 68 = 2
2/14 = 0.143 m/s
Answer:2.517 J/K
Explanation:
Given
Reservoir 1 Temperature 
Reservoir 2 Temperature 
Let Q is the amount of heat Flows i.e. 
thus change in Entropy is given by 



<span>The acceleration of an object is equal to the change in velocity over time. Or alternatively, the acceleration of an object is equal to the initial velocity minus the final velocity over the time taken to change from the initial velocity to the final velocity.</span>
