when two sine waves are superimposed on one another, a beat pattern is observed . this beat pattern consists of high intensity and low intensity in sequence alternately. we get the high intensity pattern when the two waves meet in phase and we get low intensity when the two waves are out of phase. the intensity is lowest when the two wave are completely out of phase or 180 degree phase difference between the waves.
hence correct choice is a.180
A scientific journal article that is peer reviewed. This is because it is more likely not have factual information and sources to that information.
P = mv
v = p/m
v = (25 kg m/s) / (12.0 kg)
v = 2.08 m/s
v = 2.1 m/s
Answer:
none. 0. for work to be done the object has to have displacement, and even though you were exerting force, the box did not move and s work is o it could also be 50 but I'm sure it is 0
