Ice, when matter is solid particles are closer together.
It’s related to sound frequency! Hope this helps!
Answer:
![V_{A/E}=55.23km/h\\or\\V_{A/E}=15.342m/s](https://tex.z-dn.net/?f=V_%7BA%2FE%7D%3D55.23km%2Fh%5C%5Cor%5C%5CV_%7BA%2FE%7D%3D15.342m%2Fs)
Explanation:
The velocity of plane relative to earth is given by:
![V_{P/E}=\frac{d}{t}\\V_{P/E}=\frac{[-121i-20j]km}{0.490h} \\V_{P/E}=[-247i-41j]km/h](https://tex.z-dn.net/?f=V_%7BP%2FE%7D%3D%5Cfrac%7Bd%7D%7Bt%7D%5C%5CV_%7BP%2FE%7D%3D%5Cfrac%7B%5B-121i-20j%5Dkm%7D%7B0.490h%7D%20%20%5C%5CV_%7BP%2FE%7D%3D%5B-247i-41j%5Dkm%2Fh)
As the from given data.The velocity of plane relative to air is:
![V_{P/A}=[-210i]km/h](https://tex.z-dn.net/?f=V_%7BP%2FA%7D%3D%5B-210i%5Dkm%2Fh)
According to relative motion of velocity of the air relative to earth given by:
![V_{A/E}=V_{P/E}-V_{P/A} \\V_{A/E}=[(-247i-41j)km/h]-(-210i)km/h\\V_{A/E}=[-37i-41j]km/h\\](https://tex.z-dn.net/?f=V_%7BA%2FE%7D%3DV_%7BP%2FE%7D-V_%7BP%2FA%7D%20%5C%5CV_%7BA%2FE%7D%3D%5B%28-247i-41j%29km%2Fh%5D-%28-210i%29km%2Fh%5C%5CV_%7BA%2FE%7D%3D%5B-37i-41j%5Dkm%2Fh%5C%5C)
The magnitude is given as:
![V_{A/E}=\sqrt{(37)^{2}+(41)^{2} }\\ V_{A/E}=55.23km/h\\or\\V_{A/E}=15.342m/s](https://tex.z-dn.net/?f=V_%7BA%2FE%7D%3D%5Csqrt%7B%2837%29%5E%7B2%7D%2B%2841%29%5E%7B2%7D%20%20%7D%5C%5C%20V_%7BA%2FE%7D%3D55.23km%2Fh%5C%5Cor%5C%5CV_%7BA%2FE%7D%3D15.342m%2Fs)

Explanation:
A bunch of Musical instruments have been using Resonance to make the sound louder like to amplify the instrument of their sound waves, For example- The strings that go on the Violin would be an Acoustic resonance and so is the Body of the violin cause that is where the sound waves hit to make that beautiful sound that comes out once you play the instrument!
Answer:
Las moléculas en el aire dispersan más la luz azul del sol que la luz roja. Cuando miramos hacia el sol al atardecer, vemos colores rojo y naranja porque la luz azul se ha dispersado y lejos de la línea de visión.
