Two waves travel simultaneously through the same medium. The first wave is described by y 1( x, t) = (1.00 cm)cos( kx- t)and the second wave by y 2( x, t) = (8.00 cm)sin( kx- t). What is the amplitude of the resulting wave (in cm)?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

i don't understand. explain it clearly

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
