In the figure below, a ball of density 600 kg/m3 and volume 5 x 10(-3) m3 placed in a water container. (Density of water is 1000 kgm3.) Calculate the buoyant force exerted on the ball.

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
