Answer:
Explanation:
Environmental damage from air pollution is reduced. ... Power plants have cut emissions that cause acid rain and harm public health. ... Actions to protect the ozone layer are saving millions of people from skin cancers and cataracts. ... air quality standards set to protect public health and the environment.
This is an example of classical conditioning, and the library is a conditioned stimulus.
The idea of classical conditioning was first put forward by the man Ivan Pavlov, a Russian physiologist.
In his studies, he was able to successfully associate a once neutral stimulus to a conditioned response. The neutral stimulus hitherto does not produce the expected response until after conditioning has taken place.
In this case, the library was a neutral stimulus. When it becomes associated with a bakery, it provokes the conditioned response of hunger any time you go to the library.
The library is now a conditioned stimulus.

Displacement vectors of 6 km South 2 km North, 7 km South, and 5 km North combine to a total displacement of 6 km South.
Answer: Option A
<u>Explanation:</u>
The displacement vector represents the location change: the distance of separation from the start point to the end point is the displacement vector’ magnitude, and travelled direction denotes the displacement vector’ direction.
In figure, the illustration shows a new vector for the entire journey from beginning to end. In other words, C = A + B. The C vector is called the sum, or resultant vectors. When applying this concept to the given question, we can find the total displacement vector value. It is as follows:
Given:
6 km South 2 km North, 7 km South, and 5 km North
Total displacement, s = 6 km South - 2 km North + 7 km South - 5 km North
North and south lie in an opposite direction. Therefore, when combining all distances negative sign mentioned to denote the direction.
Total displacement, s = 13 km South - 7 km North
Total displacement, s = 6 km South
What is the magnetosphere, and how does it help the earth?
The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun. ... It is generated by the convective motion of charged, molten iron, far below the surface in Earth's outer core.
