In the distant future, a base has been constructed on the moon. Inside the base, a ball is dropped into a container of water.
Given that the acceleration due to gravity is about one-sixth the value on the Earth's surface, which of the following statements correctly describes the buoyant force on the ball?

a) The buoyant force is equal to 1/6 the weight of the displaced water.
b) The buoyant force is equal to 1/6 the weight of the ball.
c) The buoyant force is equal to the weight of the displaced water.
d) The buoyant force is equal to 6 times the weight of the displaced water.

Which of the following harmful chemicals are found in tobacco smoke? a. carbon monoxide b. carbon dioxide c. nicotine b. carbon dioxide d. both a and c

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.
