The best position for the person would be outside, under a clear sky, standing up. He should do it sometime between sunset and sunrise, from a day before until a day after the moment of Full Moon.
Answer:
The speed of the wave is 128.94 m/s
Explanation:
Use the relationship between wavelength (lambda) and frequency (f) that are in a mutually reciprocal relationship via the speed of propagation:

The speed of the wave is 128.94 m/s
Answer:
It will take 60 hours to pass your area
Explanation:
From the question we are told that
The the distance of wispy cirrus clouds is 
The slope is given as 
The speed is 
Since the slope is 1:300 which indicates the change in the distance of the wispy cirrus clouds overhead to the distance of the warm front
Now if
1 km → 300 km
Then
→ x km
Cross multiplying and making x the subject

Velocity is mathematically denoted as

Now making time the subject

Now substituting values we have
