Answer:
shorter wavelength = alpha wave
Explanation:
Given that,
The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.
We need to compare the wavelengths of these two waves.
For alpha wave,
For beta wave,
From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.

D. uranium: atomic number 92, mass 238, neutrons 146
238-92=146
Answer:-
0.231 moles
Explanation:-
From the question we are told that
Volume of HCl solution = 0.70 L
Strength of HCl solution = 0.33 M
Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L
Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution
= 0.70 L x 0.33 moles / L
= 0.231 moles.
0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution
