It pushes the currents to opposite sides
The amplitude is from the absolute value of the 0 point on the y-axis to the highest(peak) or lowest(troph) point of the wave. In this question, 3cm is the highest and -3cm is the lowest, so the amplitude is 3cm.
It would be best to cover the cardiac, smooth, and skeletal muscles! =)
