Answer:
The wavelength of the radio wave is 3.003 m.
The energy of the radio wave is 
.
Explanation:
Frequency of the radio waves, ν = 99.9 MHz = 
Wavelength and frequency are related to each other by realtion:
= Wavelength of the wave
c = speed of the light
ν = Frequency of the wave
The wavelength of the radio wave is 3.003 m.
The energy of the electromagnetic wave is given by Planck's equation:
h = Planck's constant = 
The energy of the radio wave with 99.9 MHz frequency will be:
The energy of the radio wave is .
The answer is A ( pure water has no free ions)
Answer:
Nitrogen fixation is a chemical process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil or aquatic systems. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.
Explanation:
Answer:
The new molarity is 0.614 M
Explanation:
Formula for dilutions is:
M concentrated . Volume of conc = Volume of dil . M diluted
6.54 M . 249 mL = 416 mL . M diluted
Notice that volume of diluted is = Initial volume + What we added of water
(249mL + 167 mL)
(6.54 M . 249 mL) / 416mL = M diluted → 0.614 M
Lovely song just asking is there a question so I don't get hate for not knowing rather there's a question or not
