9.In the International Space Station which orbits Earth, astronauts experience apparent weightlessness because (a) the station is so far away from the center of the Earth. (b) the station is kept in orbit by a centrifugal force that counteracts the Earth's gravity. (c) the astronauts and the station are in free fall towards the center of the Earth. (d) there is no gravity in space. (e) the station's high speed nullifies the effects of gravity.

Question

9.In the International Space Station which orbits Earth, astronauts experience apparent weightlessness because (a) the station is so far away from the center of the Earth. (b) the station is kept in orbit by a centrifugal force that counteracts the Earth's gravity. (c) the astronauts and the station are in free fall towards the center of the Earth. (d) there is no gravity in space. (e) the station's high speed nullifies the effects of gravity.

Answer 1

The correct answer is (c) the astronauts and the station are in free fall towards the center of the Earth.In the International Space Station (ISS), astronauts experience apparent weightlessness because the station and its occupants are in a continuous state of free fall towards the center of the Earth. This free fall creates a microgravity environment where objects and people appear to be weightless. The station's orbit keeps it in this constant state of free fall, creating the sensation of weightlessness for the astronauts onboard.
