D, I hope this is correct!
Answer:
No its wrong
Correct compression is 0.41
Explanation:
After jumping from 2m height on spring attached platform platform is compressed a distance x(let).
So work done by gravity on Jim is converted into spring potential energy.
k=8000 N/m
mass of Jim =50 kg
Solve this quadratic one solution is positive and other is negative.
positive one is our answer = 0.41 m
The Atlantis spacecraft carried the first space lab.
Answer: Option 4
<u>Explanation:
</u>
The first space lab is named as ATLAS 1 which is the abbreviation of Atmospheric Laboratory for Applications and Science. It is a short space lab set up in space to observe the atmospheric changes and other scientific experiments in the outer atmosphere of Earth from space.
It contains hi-tech instruments and facilities. It was a part of Phase I of NASA’s mission to planet Earth. This helped in better understanding of Earth’s outer and inner atmosphere. So, the spacecraft used to carry the ATLAS 1 is named as Atlantis.
