Einstein’s theory can found E = mc 2
Issac Newton was found universal gravitional (gravity) opinion.newton’s laws can be revised over time, but einstein’s theory of relativity
If both waves have the same wavelength, then the amplitude of
their sum could be anything between 1 cm and 9 cm, depending
on the phase angle between them.
If the waves have different wavelengths, then the resultant is a beat
with an amplitude of 9 cm.
Consider the formula ...
Current = (voltage) / (resistance) .
If the resistance doesn't change, then the current is
directly proportional to the voltage.
If the voltage decreases to 1/3 of what it used to be,
then the current does the same thing.
