Given:
mass of ice melted,
time taken by the ice to melt,
latent heat of the ice,
Now the heat rejected by the Carnot engine:
Since we have boiling water as hot reservoir so:
The cold reservoir is ice, so:
Now the efficiency:
Now form the law of energy conservation:
Heat supplied:
where:
heat supplied to the engine
Now the work done:
Answer:
Current through the surface at t = 1.1 s is 21.37 A.
Explanation:
The charge is passing through a surface of area varies with time as :
Here,
t is in seconds
The rate of change of electric charge is called electric current. It is given by :
At t = 1.1 s, Current,
So, the instantaneous current through the surface at t = 1.1 s is 21.37 A.
