Question

The formula v=0. 83B^3/2 represent the wind speed, v, in relation to b, the Beaufort scale number Determine the Beaufort scale number when the wind speed is 9. 4 meter per second

Answer 1

5.0

Explanation:

You want the Beaufort scale number corresponding to 9.4 m/s, given the formula ...

v = 0.83B^(3/2)

Solution

Put the given speed in the formula and solve for B.

9.4 = 0.83B^(3/2)

9.4/0.83 = B^(3/2)

B = (9.4/0.83)^(2/3) ≈ 5.043

The wind speed is about 5.0 on the Beaufort scale.
