Answer: With the discovery of plate tectonics and the mapping of the earth into about 12 plates, plus the understanding that plates' movement caused earthquakes, Alfred Wegener's idea of " continental drift" looked less ludicrous than his contemporaries had thought.
Explanation: Hope this works :)! If not, I am sorry :(. If it does, Your Welcome! :)
Answer:
a) n2 = 1.55
b) 408.25 nm
c) 4.74*10^14 Hz
d) 1.93*10^8 m/s
Explanation:
a) To find the index of refraction of the syrup solution you use the Snell's law:
(1)
n1: index of refraction of air
n2: index of syrup solution
angle1: incidence angle
angle2: refraction angle
You replace the values of the parameter in (1) and calculate n2:

b) To fond the wavelength in the solution you use:

c) The frequency of the wave in the solution is:

d) The speed in the solution is given by:

Answer:
They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time.
Answer:
The value is 
Explanation:
From the question we are told that
The diameter of the storm is 
The wind speed is 
Generally the radius is mathematically represented as

=> 
=> 
Generally the angular velocity is mathematically represented as

=>

Answer:
The second one
Explanation:
The second one is joining so it is the one which belongs to X, first one belongs to Z
