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.
Answer:
Q = 2997.69 J
Explanation:
Given that,
The mass of ice, m = 15.6 grams
The temperature increases from -8.76 degrees Celsius to 85.9 degrees Celsius.
The specifc heat of ice is 2.03 J/g°C
We need to find the amount of energy required. The formula for energy required is given by :

So, the required heat is equal to 2997.69 J.
30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
Static force is being exerted
