Analysis of time series data for a given site has yielded an average velocity of 6 m/s. It
is determined that a Rayleigh wind speed distribution gives a good fit to the wind data.
a) Based on a Rayleigh wind speed distribution, estimate the number of hours that
the wind speed will be between 9.5 and 10.5 m/s during the year.
b) Using a Rayleigh wind speed distribution, estimate the number of hours per year
that the wind speed is equal to or above 16 m/s.
It was reported that on a particular day in Saint Cloud MN, the atmospheric pressure
was 94,980 Pa at the ground level. If a student measured with a barometer and find
the pressure to be 94,760 Pa, approximately how high above ground was she making
the measurement?
Assume atmospheric pressure decreases 11.7 Pa per meter of altitude increase
during that day.
This was wrong. Can you solve this again with these numbers?

- Can you please clarify how to do these graphs? I think I've got the first two done, but then they start getting complicated, and I my scales are messed up. I have a program I can run to look at the answers, so getting the correct answer is not the problem, but can you tell me how to do them? And then I don't fully understand how to describe them either as I am instructed to do. Thank You!arrow_forwardand electrocardiogram is recoreed on mm-grid chart paper moving at a speed of 25mm/s.

The cycle of inhalation and exhalation during normal activity can be represented as a sine curve, as shown in the figure below, where the amount of air in each lung before inhalation begins is about 1.09 liters (the functional residual capacity of the lung) and the time on the horizontal axis has been calculated with the average adult breathing rate of 16 breaths per minute.
