A small satellite orbiting the earth has only one window for the astronaut and window is facing away from earth. Explain how the astronaut can rotate the satellite so he can view the earth and not use any rocket fuel in d process...

By crawling along the floor..
since if he moves in one direction, the floor and thus the satellite) will rotate in opposite direction

by operating a taperecorder, so that the the satellite rotates in the opposite direction of rotation if the tape recorder casette

The astronaut or rather shall I say the astro*nut*( btw who travels in a spacecraft with just a small window??) should rotate something circular which can act as a flywheel and spin it in the opp dir of the dir he wants the spacecraft to spin in

The trouble with doing something right the first time is that nobody appreciates how difficult it is.
You can't control the wind, but you can adjust your sails.

@ Gaurav -- If he crawls along the walls(spidey unlimited!), won't he move away from the window and he'll waste his energy for nothing

Shinee is actually correct
Besides some good music, the tape recorder will make the satellite rotate in the opposite direction in order to conserve angular momentum

arre yaar conservation of momentum ....

FAILURE IS NOT FALLING IN LIFE BUT NOT RISING AGAIN AFTER FALLING!!!!!!

The concept of rotation is good, but i would like to raise one more pont. If satelite is thrown in the space with no angular velocity about it axis then its window will face once in every revolution. So astronaut should wait for half revolution when earth will come to the windows side.
