Answer:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. ... The more rigid (or less compressible) the medium, the faster the speed of sound
Explanation:
Answer:
Antibiotics are strong medicines that treat bacterial infections. Antibiotics won't treat viral infections because they can't kill viruses. You'll get better when the viral infection has run its course. Common illnesses caused by bacteria are urinary tract infections, strep throat, and some pneumonia.
Explanation:
antibiotics can treat bacterial infections, such as:
Most sinus infections.
Strep throat.
Urinary tract infections.
Pneumonia.
Most ear infections (otitis media)
Nasty bacterial skin infections (impetigo)

Answer:
5.66
Explanation:
sin = opposite/hypotenuse
8 sin = opposite
8 sin 45 = 5.66
2H2O+O2--->2H2O2
8.5 gm H2O2=0.25 mole
hence H2O is also 0.25 mole i.e.4.5 gm
O2is 0.125 mole i.e.4 gm
We know the sun is primarily made from hydrogen and helium on the basis of its spectrum.
<h3>What is Sun's spectrum?</h3>
Sun's spectrum refers to the light of the Sun whose wavelength spectra can be used to identify atomic composition.
Thus spectrum (Sun's spectrum) initiates with the red light (700 nm) and ends with the blue (380 nm).
In conclusion, we know the sun is primarily made from hydrogen and helium on the basis of its spectrum.
