B would be your right answer. Because Jupiter’s gravity pull is much stronger than earths
Answer:
Explanation:
As we know that initial angular speed of the tub was zero and then it increases uniformly to 4 rev/s in t = 6.00 s
so we will have
Now when the tub will comes to rest uniformly after opening the lid in time interval of t = 15 s
then we have
Now total angular displacement of the tub is given as
so number of revolutions is given as
The answer is C due to the kinetic movement of the rc car driving around and the electrochemical energy turning into electrical energy.
