Question

The blades of a helicopter rotate at an average rate of 500 rotations per minute. What is the frequency of rotation of blades

Answer 1

Answer: f=8.333 rotations/sec

Explanation:

Given that,

Rotations made per minute=500

To find: frequency of rotation of blades=?

We know,

Frequency(f)=No of cycles/ second........(1)

Now, 1 minute=500 rotations

Or, 60 seconds=500 rotations

Or, 1 second=500/60 rotations =8.3333 rotations

Therefore, f=8.333 rotations/second

Answer 2

Answer:

Explanation:

Given that,

Rotations made per minute=500

To find: frequency of rotation of blades=?

We know,

Frequency(f)=No of cycles/ second........(1)

Now, 1 minute=500 rotations
