Answer:
no it is not 2D
Explanation:
it is 3D
ok so follow these steps
- make hole
-make square
-make triangle
ok now your figure is ready
The system includes a disk rotating on a frictionless axle and a bit of clay transferring towards it, as proven withinside the determine above.
<h3>What is the
angular momentum?</h3>
The angular momentum of the device earlier than and after the clay sticks can be the same.
Conservation of angular momentum the precept of conservation of angular momentum states that the whole angular momentum is usually conserved.
- Li = Lf where;
- li is the preliminary second of inertia
- If is the very last second of inertia
- wi is the preliminary angular velocity
- wf is the very last angular velocity
- Li is the preliminary angular momentum
- Lf is the very last angular momentum
Thus, the angular momentum of the device earlier than and after the clay sticks can be the same.

I think option c 12 is currect
Answer and Explanation :The universe means it includes everything, even the things which we can not see is an isolated system because universe has no surroundings. an isolated system does not exchange energy or matter with its surroundings.Sometime universe is treated as isolated system because it obtains lots of energy from the sun but the exchange of matter or energy with outside is almost zero.
- the total energy of an isolated system is always constant means total energy of universe is also constant
- there is no exchange of matter or energy in an isolated system
