2. Read the following experiment. Describe the experiment's results; identify which of
Newton's laws is illustrated and how these results support this law. (10 points)
A karate master can exert a tremendous force by utilizing years of training, proper technique,
and focus. Although a human hand and forearm may have a mass of 0.75 kg, with proper
technique a karate sensei (master) will be able to use his entire body's mass to break bricks.
Combining all his abilities, this master will exert 3,500 N of force, far more force than is
needed to break several bricks.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
