What happens to astronauts in space for a long period of time?
Their bones, heart, and muscles begin to waste away because they cannot strengthen themselves by working against Earth's gravity; if they return from over 8 months in space, their bones would instantly break. It's not a pretty picture.
Why did astronauts back in 1960s return to earth with muscles so weak that they had difficulty walking when they returned to the earth?
After any period in a place where the force of gravity is less than on the surface of the earth (or nearly weightless in orbit), muscles will begin to atrophy. The longer in space the weaker you get becuase the muscles do not have to counter the force of gravity. This also includes the heart muscle so the astronauts must be monitored while in space and for a while after their return to earth.
When a satellite is placed into a higher orbit what happens to its period?
Its period increases
What happens to the sun when the distance increases orbital period of planet?
If a planet's distance from the sun would increase, its revolutionary path would be extended (because it would have to traverse more distance), ergo increasing its period of revolution. Take an ellipse and enlarge it, then measure the perimeter of each ellipse, the larger one will have a larger perimeter.
What physical changes happen to your body during and after space travel?
One major one is not being able walk or stand up if they have been in space for an extended period of time. This is because they have gotten used to weightlessness in space and muscles atrophy a bit. It does take an extended period of time for this to happen.
What happens to the muscles of astronauts who are in space for an extended period?
They weaken
What happens to the muscle of astronauts who are in space of an extended period?
Astronauts' muscles atrophy in space due to the decreased work they do without Earth's gravity.
What happens to muscles when they are not challenged for an extended period of time?
they become flabby and smaller.
What happens to leg muscles due to the disuse of these muscles over a long period of time?
Atrophy
When a joint is immobilized for an extended period of time the muscles around that joint undergo a process called?
Atrophy
What term describes the ability of the heart and lungs to supply oxygen to the muscles for an extended period of time?
cardiovascular fitness
What happens when hyperinflation occurs over an extended period of time?
Everybody dies. That's it.
What happens to the muscles of astronaunts who are in space for an extended period?
they weaken Because there is no gravity in space muscles go unused. Because of the lack of use they weaken and even begin to deteriorate. Astronauts must exercise for hours daily in order to maintain there strength.
What happens if the force of impact is extended over a period of time?
if force of impact is extended over period time the country might be destroy like what happen o Haiti .
When muscles are used for and extended period of time what builds up in the muscle tissue?
That is lactic acid. This is what produces a "burning" feeling.
Why must there be pressurized cabins in space crafts?
If it wasn't pressurised there would be no air and the astronauts would die. Of course they could keep their spacesuits on but that would not be comfortable for an extended period of time.
