Q. The magnitude of F is 306 newtons and it points at 93o measured counter clockwise from the positive x-axis. What is the y component (in newtons) of F?
Q. Two sound sources radiating in phase at a frequency of 500Hz interfere such that maxima are heard at angles of 0° and 24.50° from a line perpendicular to that joining the two sources. The listener is at a large distance from the line through both sources, and no additional maxima are heard at angles in the range 0° < θ < 24.5°. Find out the separation d between the two sources and any other angles at which intensity maxima would be heard. Utilize the following result.
