My guess would be because the gravity from the Earth's core is constantly pulling the ball towards the ground. It's like the moon. Why doesn't the moon just float away in space? Because Earth's gravitational pull keeps it rotating around it. Therefore, the ball will always be pulled towards the core which keeps it from from rolling forever due to friction. But i may be wrong, even though this a quite a good answer, hope it is right!
The answer would be D) Kinetic friction because kinetic means during and in motion and happening/occurring so since the box is moving now across the floor, its in motion so that's why its D).
Answer:
Heat transfer in the process is -19.6 kJ
Work done in the process is - 28 kJ
Explanation:
As we know that the process equation is given as
now we know that
now from above equation we have
now work done in this process is given as
here we know N = 1.1
so we have
Now we have
now we have
so we have
