Answer:
D) it turns steam when released
Explanation:
In a nuclear reactor, the superheated water leaving turns to steam when released and it in turn is channeled to turn turbines in order to produce electricity.
- A nuclear reaction is used to generate current through a series of processes.
- The reaction produces a significant amount of heat energy.
- This heat energy is used to superheat water and convert it to steam.
- The steam is then channeled to drive turbines whose mechanical rotation produces electricity.
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies.
Answer:
Option C.
Explanation:
Physiographic, is the right answer.
A map which exhibits the land-forms and physical features of an endorsement is known as the Physiographic map. Such maps reveal the position of valleys, mountain ranges, and other natural features of the surface of Earth. It shows the complete physical shape or the land-form sections of a nation. Various colors are used to represents a different physical region.
Answer:
"All of them except last one."
Explanation:
All of the given options represent NASA future projects:
- Use a probe to collect data- Parker Solar Probe will be the first-ever mission to study the Sun from such a small distance. The spacecraft will travel directly into the Sun's atmosphere about 4 million miles from the surface.
- Improve aviation technology- NASA is currently working on the development of the new experimental aircraft X-plane which will prove the dramatic benefits of advanced technologies in piloted flight.
- Conduct research from a space station- Humans are already living and working on board of the International Space Station which is one-of-a-kind research laboratory in micro gravity. A portion of the astronauts time aboard the space station has been designated for national laboratory investigations.
- Collect samples on an asteroid- First asteroid sample return mission, OSIRIS-R Ex, arrives at the near-Earth asteroid Bennu in December 2018 and should return a sample for study in 2023.
- Conduct an unmanned space mission- In Sight Mars lander is set to study the planet’s interior. The Mars 2020 rover will search for signs of past microbial life, gather samples for future return to Earth and investigate resources. The James Webb Space Telescope will be the premier observatory of the next decade, studying every phase in the history of our Universe in infrared
