Based on archimedes' principle, the greatest buoyant force an object can experience in water is determined by which quantity? a. the object's mass b. the object's chemical properties c. the object's volume d. the object's pressure

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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
