Will the astronaut interfere with the swelling of his feet in space ? Why?
Answers
Answer :-
a) We know that the legs carry the weight of the body in the normal position due to gravity pull. The astronaut in space is in weightless state. Hence, swollen feet may not affect his working.
(b) In the condition of weightless, the face of the astronaut is expected to get more supply. Due to it, the astronaut may develop swollen face. As eyes, ears,noes, mouth etc, are embedded in the face , hence swollen face may effect to great extent the seeing/hearing/smelling/eating capabilities of the astronaut in space.
(c) Headache is due to mental strain. It will persist whether a person is an astronaut in space or he is on earth. It means headache will have the same effect on the astronaut as on a person on earth.
(d) Space also has orientation. We also have the frames of reference in space. Hence, orientational problem will affect the astronaut in space
