Answer:
IV: speed of the fan
DV: time of cup ascent
Explanation:
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. As the speed of the fan increases, so does the kinetic energy, then it transfers energy to the Cup ascent.
Frequency can be found by counting the number of troughs per second in a wave diagram.
Reached equilibrium, the positive and negative charges cancel or balance each other out.
