the mean sustained wind velocity, v, can be determined by the equation $v = 6.3sqrt{1013 - p}$, 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?\n103 millibars\n194 millibars\n363 millibars\n910 millibars
Answer
Explanation:
Step1: Substitute given value of v
Given $v = 64$ and $v=6.3\sqrt{1013 - p}$, so $64 = 6.3\sqrt{1013 - p}$.
Step2: Isolate the square - root term
Divide both sides by 6.3: $\frac{64}{6.3}=\sqrt{1013 - p}$. So, $\sqrt{1013 - p}\approx10.1587$.
Step3: Square both sides
$(\sqrt{1013 - p})^2=(10.1587)^2$. Then $1013 - p\approx103.2$.
Step4: Solve for p
$p = 1013- 103.2$. So, $p\approx910$ millibars.
Answer:
910 millibars
