Δλ = 3.103 m.
To solve this problem we have to know the speed of sound in both elements water and ice.
Element Speed of sound
Water (25°C) 1493 m/s
Ice 3200 m/s
The velocity of a wave is given by the equation v = λf, where λ is the wavelength, and f is the frecuency of the wave.
In order to calculate the wavelength we have to clear λ in the equation v = λf, resulting:
λ = v/f
Calculating the wavelength in both elements:
λ(water) = 1493 m/s / 550 Hz = 2.715 m
λ(ice) = 3200 m/s / 550 Hz = 5.818 m
So, the difference in wavelength between the wave produced in ice and the wave produced in water is:
Δλ = λ(water) - λ(ice) = 5.818 m - 2.715 m
Δλ = 3.103 m
Poor diet is predominantly associated with weight gain and obesity; however, the harmful effects do not end there. Animal and human studies indicate that an unhealthy diet can contribute to the development of many diseases, like cardiovascular disease and cancer, and can even affect the brain.
I think the answer is A
.
im not the best with physics but i think its right
