What is the wavelength of a wave with a frequency of 0.4 kHz traveling at 16 m/s?
larisa86 [58]

Answer: 0.04metres

Explanation:

The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ

Recall that Velocity (V) = Frequency F x wavelength λ

V = F λ

Make λ the subject formula

λ = V / F

In this case Frequency = 0.4 kHz

Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz

Velocity of wave = 16 m/s

So, λ = V / F

λ = 16 m/s / 400Hz

λ = 0.04metres

Thus, the wavelength of a wave is 0.04metres

How does the sea ice in 2019 compare to the sea ice in 2012 during April?
Katarina [22]

The total amount of sea ice showed a decline from 2012 to 2019. The correct option would be D.

<h3>Graphical illustration</h3>

Looking at the graph, from February to June 2012, there is a decline in the amount of sea ice.

A similar decline in the amount of sea ice can be observed in the year 2019.

However, the sea ice levels for the various months in 2012 remain generally above the sea ice levels in the various months in 2019.

Thus, overall, one can say there is a general decline in the ice level from 2012 to 2019.
