A wave having a wavelength of 1.5 meters and amplitude of 3.0 meters travels a distance of 15 meters in 3.0 seconds. Determine the frequency
and the period of the wave. *
Your answer

velocity, v = 15m / 3.0s

= 5 ms^-1

velocity = wavelength × frequency

5 ms^-1 = 1.5m × f

f = 5 ms^-1 / 1.5 m

f = 3.33 Hz

f = 1/T

T = 1/f

= 1/ 3.33 Hz

= 0.3 s

frequency, f = 3.33 Hz

period, T = 0.3 s

Explanation:

Carbon is an essential element in the bodies of living organisms. It is also economically important to modern humans, in the form of fossil fuels.

Carbon dioxide {CO}_2CO 2

Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.

Some human activities, such as the burning of fossil fuels and deforestation, increase atmospheric {CO}_2CO2
