Answer:
Temperature of the sink will be 191.1 K
Explanation:
We have given that heat withdrawn form the source = 10 KJ
Work done = 3 KJ
We know that efficiency is given by
Higher temperature is given by 
We have to find the lower temperature 
We know that efficiency is also given by
So 
So temperature of the sink will be 191.1 K

In many physical situations, an object will be subject to many different forces such as gravity, friction or an external force. Finding the sum of these forces ultimately indicates if the object will move and in what direction it will move in. The sum of all forces that act upon an object is known as the net force. It can be found by simply adding individual force vectors together.
A right turn would be the answer probably.
