The sun currently rotates once every 24.47 days. The solar radius is 6.963x10^8 m. As the Sun ages it will evolve into a type of star called a red giant. Astrophysicists estimate that when the Sun reaches this phase of its life, its radius will be at least as large as the distance from Venus to the Sun, engulfing the planet. The distance between Venus and the Sun is 1.081x10^11 m. How many days will it take for the Sun to rotate with its new radius?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

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?
