All of the objects are falling from the same height. Which statement is true about their motion? A. The force of gravity keep them apart.
B. They are all falling at the same rate do to the acceleration of gravity
C. They are falling at different rates due to their masses being different.
D. The speed will vary due to their shapes.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
