Answer:
b. Antarctica's ice
Explanation:
Earth is flatter at the South Pole than the North Pole because of the weight of the Antarctica's ice.
The Antarctica ice cap is the largest single mass of ice on earth. It covers almost 14 million square kilometers and it weighs 26,500,000 Gigatons.
As a result of this heavy weight, it compresses the South Pole of the earth causing the earth to be flatter at the South Pole.
This gives the Earth its slight pear shape.
Answer:
it is 6 feet long
Explanation:
Pythagorean Theorem tells that in a right angled triangle, sum of the squares of two perpendicular lines is equal to the square of hypotenuse.
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
