Identify which one of these systems can be considered as constituting an isolated system.
| Two marbles colliding on a sandy beach. The two marbles are the system and the sandy beach is external to the system. |
| Two motorcycles colliding on a rubber surface offering a large friction force. The system is the two motorcycles and the rubber surface is external to the system. |
| Two pucks colliding on a sticky surface. The two pucks are the system and the sticky surface is external to the system. |
| Two pucks colliding on a frictionless ice surface. The two pucks are the system and the ice surface is external to the system. |
Homework Answers
A system is said to be an isolated system when it is free from any net external force which can change the momentum of the system.
------------------------------------------------------------
I think option (D) is correct because it has not external forces like friction acting on it.
all other options have a lot of friction between surfaces.

Problem 1 Two identical pucks, each of inertia m, are connected to a rod of length 2r and negligible inertia that is pivoted about its center (that is, there is some sort of pin though its center, around which it can rotate without friction). A third puck of inertia m/2 strikes one of the connected pucks perpendicular to the rod with a speed vi. Assume the collision is elastic. (a) Draw a diagram of the situation, clearly labeling the direction...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
