Question

The mean sustained wind velocity, v, can be determined by the equation v=6.3square root 1013-p, where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?

A) 103 millibars
B) 194 millibars
C) 363 millibars
D) 910 milibars

Answer 1

the answer is d on the test

Explanation:

Answer 2

The mean sustained wind velocity has the equation:
v = 6.3 √(1013 - p)

If we are given with the mean sustained wind velocity of 64 m/s, then we can solve for the air pressure using the equation:
64 = 6.3 √(1013 - p)
64/6.3 = √(1013 - p)
10.1587² = 1013 - p
p = 910 millibars
