Answer:
0.1371 * 10 ^ -27 kg
Explanation:
From the question number of hydrogen nuclei used to form 3 Helium nuclei = 12 ( 4 * 3 )
mass of the 12 hydrogen nuclei = 12 *( 1.6726 *10^-27) = 20.0712 * 10 ^-27
mass of single helium = 6.6447 * 10 ^-27 kg
therefore the mass of the 3 helium = 3 *( 6.6447 *10 ^-27) = 19.9341 * 10 ^-27 kg
The mass difference between the hydrogen and the helium used
= (20.0712 * 10^ -27) - (19.9341 * 10 ^-27) = 0.1371 * 10 ^ -27 kg
therefore 0.1371 * 10^-27 kg is converted into energy to create the three helium nuclei
L=G·d
L=600N·3m=1800J
P=L/Δt=1800J/4s=450W
When two sound waves of similar frequency interfere with each other, there is a fluctuating sound heard which is periodic and repeating. This fluctuating sound is called beat. Beat frequency( number of beats per second) is equal to the difference of the frequency of the two sound waves.
So, sound waves of frequency 400 Hz and 404 Hz will produce 4 beats per second.
