Which of the followings (one or more) are the experiences as shared by Sunita Williams after her space journey?

evs - i universe and space science human beings in space our pride - iii our scientist

  1. "We could not sit at one place. We kept floating in the spaceship from one end to another"

  2. "Water doesn't stay at one place. It floats around as blobs."

  3. "There was no need to use a comb. My hair kept standing all the time"

  4. All of the above

Show answer
Correct Option: D
Explanation:

There is no gravity in space, so the objects keep floating in space due to lack of gravitational force. Sunita Williams wanted to show that objects kept floating in space. She shared some experiences that they kept floating in spaceship, water floats around as blobs, her hair kept standing all the time in spaceship etc.
