I need help with question ii) Calculate the speed of these radio waves.
I don't know if I started it right.... I need help plss!!!
Answer:
Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.
If two waves interact in destructive interference, which of the following will be true regarding the new wave formed?
A. The new wave will produce a lower-pitched sound than the two original waves.
B. The new wave will produce a quieter sound than the two original waves.
C. The new wave will produce a higher-pitched sound than the two original waves.
D. The new wave will produce a louder sound than the two original waves.

what are two roles of bacteria in a nitrogen cycle
Answer:Nitrogen-fixing bacteria convert free nitrogen gas into nitrogen compounds. ... Bacterias that are decomposers recycle nitrogen compounds in the soil by breaking down animal wastes and dead plants and animals. 3. Other bacteria break down nitrogen compounds and release free nitrogen back into the air.
Explanation:
"The nitrogen fixing and bacteria of decay" is the two major role of bacteria in nitrogen cycle."
What is nitrogen fixing?Nitrogen fixing can be define as the process in which It is possible to see nitrogen converting to nitrate.
What is bacteria of decay?Bacteria of decay can be define as the process in which it is possible to see nitrogen waste converting to ammonia.
What is nitrogen?Nitrogen can be referred as element which is kept in boron family in the periodic table.
Therefore, the two role of bacteria in a nitrogen cycle is bacteria of decay and nitrogen fixing.
