What is the period of oscillation of a pendulum that is .5m long? .26 s
1.42 s
6.28 s
13.9 s

the force on the thing and the distance the force moves the thing

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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.
