Question

In the buoyancy force formula: F_B = rho Vg, which option is the correct interpretation of the variables? a) rho is the density of the object, V is the volume of the object, and g is the to acceleration due to gravity b) rho is the density of the object, V is the submerged volume of the object, and g is the acceleration due to gravity c) rho is the density of the surrounding fluid, V is the velocity of the object, and g is the acceleration due to gravity d) rho is the density of the surrounding fluid, V is the submerged volume of the object, and g is the acceleration due to gravity If an object is observed to sink, which is true about the forces acting on it? a) weight of the objects equals the buoyant force on it b) weight of the object is less than the buoyant force on it c) weight of the object is greater than the buoyant force on it The position vs time graph for the bead falling through oil is linear. What does that tell you about the motion of the bead? a) The graphs shows the bead is accelerating as it falls b) The graph shows that the bead has reached the bottom of the graduated cylinder and its position doesn't change c) The graph shows that the bead reaches its terminal velocity quickly and continues at a constant speed after that velocity d) The graph shows the bead accelerating for most of its motion, but it does reach terminal velocity before the end of the data set

Explanation / Answer

2. d) p is the density of the surrounding fluid, V is the submerged volume of the object,and g is the acceleration due to gravity.

3. a) weight of the object equals the buoyant force on it.
