The blades of a helicopter rotate at an average rate of 500 rotations per minute. What is the frequency of rotation of blades ?
1min = 500 rotations
60 seconds = 500 rotations
1 second = 500/60 rotations
which is equal to frequency of the blades
60 seconds = 500 rotations
1 second = 500/60 rotations
which is equal to frequency of the blades
