<span>Lack
of training in getting the vital sign or worst, not knowing the right way to
take the vital sign could contribute to an inaccurate vital sign reading. For example,
if you are tasked to get the respiration of the patient, the rule is to count
inhale and exhale as one. But if you were not able to know this rule, and you
counted inhale as one and exhale as another, this could impair the vital
reading. </span>
The distance starting from the point to the lighthouse would be regarded as the hypotenuse.
And also will be the radius of the circle the beam of light is generating at that point.
So get the radius first
r = sqrt (1^2 + 5^2)
r = 5.099 km
find the circumference:
C = 2*pi * 5.099 km
C = 2 * 16.01898094
C = 32.04 km
Then find the speed in km/sec
One revolution: 60/2 = 30 sec per revolution
Speed = 32.04 km/30 sec
S = 1.068 km/sec is the speed of light
From my research, the question has the following choices:
a.the lowest frequency at which a standing wave is possible
b. the highest frequency at which s standing wave is possiblec. the only frequency at which a standing wave is possible
d. the only frequency at which standing wave is not possible
From there, the correct answer is A.
