Answer:
All of the above is the answer
Answer:
Mass of CO2 = ? Thus, the mass of 2.2x10^9 molecules of CO2 is 9.68 x 10^10 grams.
Explanation:
Answer:
Explanation:
In this reaction, calcium is balanced in either side. No. of atoms of 'H' and 'O' are not balanced. To balance O atoms, multiply by 2. Now the reaction becomes:
Now, to balance H atoms, multiply H2 by 2.
Now, each element is balanced.
From the relationship between wavelength and frequency, the frequency of the wave is reduced by half to 60 Hz as the wavelength is increased twice to 10 m at constant speed.
<h3>What is the relationship between wavelength, velocity and frequency of a wave?</h3>
The velocity, frequency and wavelength of a wave are related by the formula given below:
where
- v is velocity
- f is frequency
- λ is wavelength of the wave
From the above relationship:
If the wavelength of a wave is increased to 10m but the speed stays the same at 600 m/s, the frequency can be calculated as follows:
f = v/λ
f = 600/10
f = 60 Hz
Therefore, the frequency of the wave is reduced by half as the wavelength is increased twice at constant speed.
