Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.

Answer:
When you use your control remote, you can see that there is not a "material" thing that comes out of the control remote and goes to the TV, but there is actually energy that comes from the control remote (and this is why your control remote needs battery)
This energy is called an "electromagnetic wave" usually in the infrared range, this means that the energy that comes from the control remote has less energy than the visible red light (and this is why we can not see the light that comes out of the control remote), and this "signal" is read by the TV, in order to change of channel or change the volume.
You even can see that there is a sort of light (electromagnetic wave) coming out from it if you point with a camera to the small bulb that is in the front of the control remote.
"Decimeter" is a unit of length or distance, whereas "milliliter" is
a unit of volume. They measure different quantities, and have
different physical dimensions. Neither one can be converted to
the other one.
If it were possible to convert volume to length or distance, you
(or someone with a better handle on his math and physics) could
figure out how many inches of milk you poured on your cereal.
Answer:
I think you ask for another way of writing the joule (J). It can be expressed as the product between a force applied to a body and the deployment of the body (not necessarily caused by that force applied), so N*m (newton * meter).
Answer:
The disk covers a rotation of 90º after 3 seconds.
Explanation:
Since the disk rotates at constant angular speed, we can determine the change in angular position (), measured in sexagesimal degrees, by the following kinematic formula:
(1)
Where:
- Angular velocity, measured in sexagesimal degrees per second.
- Time, measured in seconds.
If we know that and , then the change in angular position is:
The disk covers a rotation of 90º after 3 seconds.
