A beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. Frequency beat is equal to,
The reference frequency in our case would be 392Hz, and since there is the possibility of the upper and lower range for the amount of beats per second that the two possible frequencies are heard would be
Therefore the two possible frequencies the piano wire is vibrating at, would be 396Hz and 388Hz
The answer is C as there is more force on the left side ( excess of 5 N) which therefore pushed it to the right with a force of 5 N!
The answer is b or d u chooose i don’t know which one

, b) 
Explanation:
a) The heat transfered to the egg is computed by the First Law of Thermodynamics:
b) The amount of entropy generation is determined by the Second Law of Thermodynamics:
Answer:
Explanation:
As we know that the sixth order maximum will have path difference given as
here we know that
N = order of maximum
now we have
so we know that
