Answer:
Methane is a colorless, odorless flammable gas which is the main constituent of natural gas. It is the simplest member of the alkane series of hydrocarbons.
Explanation:
Answer:
a) 1.95 m/s
b) 5.56 m
Explanation:
Given that:
Velocity of the skier
= 14.3 m/s
For the skier moving in the direction of the wave, we have:
Period (T) = 0.450 s
Relative velocity (V) of the skier in regard with the wave = 
where:
= velocity of the skier
= velocity of the wave
The wavelength
can be written as:

---------------> Equation (1)
For the skier moving opposite in the direction of the wave, we have:
Period (T) = 0.342 s
Relative velocity (V) of the skier in regard with the wave = 
The wavelength
can be written as:

------------------> Equation 2
Equating equation (1) and equation (2) and substituting
= 14.3 m/s ; we have:


Collecting the like terms; we have:







b)
The Wavelength of the wave can be calculated using : 



λ ≅ 5.56 m
