Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.
Answer:D -it causes high-pressure air mASses to rotate clockwise
Explanation:
Jet stream is a very fast air stream that occurs in the upper troposphere. Jet streams occur around the earth surrounding it and following an undulating course. These air jets were discovered during the air raids in World War II.
Occurring in the upper levels of the troposphere, this current is of great importance to aviation and can be harnessed to provide fuel economy to the aircraft that penetrate them by taking advantage of the momentum provided by their intense winds. There are two types of jet stream: the subtropical jet, with higher altitude being found between latitudes of 20 ° and 30 °; and the lower altitude polar jet, being generally located between the circumpolar region and the average latitudes (40 ° -70 °). Regardless of the type, jet streams form a boundary between a cold air mass and a hot air mass.
