Both of these masks are used for dust, but since half masks are generally cheaper and easier to use, I'd go with C.
If this is correct, I'd appreciate a brainliest.

Explanation:
Press windows and prt sc at the same time
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.

Answer:
- Depletes Fossil Fuels
- Polution
Explanation:
Fossil Fuels take millions of years to be made. Gasoline is made up of primarily petroleum (a fossil fuel) which is easily refined into gasoline or kerosene. This means that once you run out of a fossil fuel...you're out of it.
Gas cars are also very big polutants. If you've ever heard of an emmisions test for a car, it is a test that sees how much pollution a car puts out into the air. It meassures how safe those levels are. This is a big indicator of how much cars pollute becasue there is a need to test your car every year. The gases that can be put into the air are harmful not only to humans and animals but to the climate and atmosphere.
