Answer:
Design 2
Explanation:
I had this same question
My answer:
"Design 2 is the well-designed one, because the air molecules are the most compact and could protect the individual better than 1,3,and no air bag."
Answer:
Acceleration, 
Explanation:
Given that,
Speed of pilot, v = 475 m/s
Radius of the circle, r = 2310 m
If the pilot is moving in a circular path, it will experience a centripetal acceleration. It is given by the formula as :
So, the acceleration experienced by a pilot flying in a circle is 
. Hence, this is the required solution.
<span>208.3 meters
The product of the wavelength multiplied by the frequency will equal the speed of light which is 299792458 m/s. Simple algebra will tell you that you can divide the speed of light by the frequency to get the wavelength. So
224997958 m/s / 1080000 1/s = 208.3314426 m
Rounding to 4 significant digits gives you 208.3 meters.</span>
The formula for Force is... F = ma or Force = mass * acceleration
Now all we need to do is substitute in the given values to find the force...
F = ma
F = 45(2)
<u>F = 90 N</u> <u></u> <---- Remember the unit for force is the Newton or N for short
