A ladybug is resting on a 0.5 meter radius turntable that is rotating with a period of 2 seconds. the ladybug is halfway between and the edge. Required:
a. What is the tangential distance travelled by the ladybug in one revolution?
b. What is the tangential velocity of the ladybug?
c. What is the angular distance traveled by the ladybug after one revolution?
d. What is the angular velocity of the ladybug?

probably not if net force is zero

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
