Why do different metals have different characteristic flame test colours? Why do different metal ions give different colors based on flame test? Explain why different elements produce different colors of light
The length of ‘x’ in ‘Y2’ is 64, so 37 elements of the original signal have been removed before the Fourier transform was calculated. To illustrate: 테마복사 Y1 = fft(x,nfft1)*dt; Y2 = fft(x,nfft2)*dt; % Fourier transforms Y3 = fft(x(1:64))*dt; % Truncate...
Do different elements have distinct atomic emission spectra? Why? Energy from radiation can cause chemical bonds to break. To break the nitrogen-nitrogen bond in N2 gas, 941 kJ/mol is required. a. Calculate the wavelength of the radiation that could break the bond...
Part 2: application to different impact sources. Acta Acustica United Acustica 2013;99.Scholl, W.: Why not use impact sound reduction indices instead of impact sound pressure levels? ActaAcustica 3, 2011Scholl, W.: Why not use impact sound reduction indices instead of impact sound pressure ...
Why are no two emission spectra for different elements ever the same? UV radiation causes poly(propene) to degrade. Suggest one advantage and one disadvantage of this. How do tsunamis affect atmosphere? Why must humans worry about the number of X-rays and CAT scans they can receive?
and equal capacity to choose among varieties suiting different needs, are yet to be overcome. While maize production and its uses in Nigeria have increased over the past decades, an important part of the Nigerian population has very limited input into making decisions around maize varieties and th...
mind how storage management has changed in recent years. The COVID-19 pandemic increased remote work, the use of cloud services and cybersecurity concerns, such as ransomware. Even before the pandemic, all those elements saw major surges -- and after the pandemic, these elements are prominent....
Clearly, the mutant alleles that occur in cancer have a very different distribution when we subset out the positions where mutations occur at the highest frequencies from the total set of mutants. There is not a simple correlation between the poorest structural p53 proteins with high VIPUR scores...
Let’s dive a little deeper and consider the main elements that affect the tone (frequency spectra) of the room itself by comparing elements of the two presets. Reflections roll-off: Boston Hall A: 15.6 kHz Boston Hall B: 10.4 kHz Discussion: The overall brightness of the reflections is ...
Why do the plasma and dust tails usually point in different directions? Define a spectrum and discuss how spectra are used in astronomy. The peak blackbody temperature of an asteroid is in the infrared. Why are they usually observed in ...
