Let us assume that the frequencies are 499Hz, 500 Hz and 501 Hz.

beat frequency = difference between the two frequencies.

Number of beats formed by 499 and 500Hz is 1.

Number of beats formed by 500 and 501 Hz is 1.

Number of beats formed by 499 and 501 Hz is 2.

Total number of beats is 1+1+2 = 4.

If you find it difficult to follow the above solution, I suggest that you first revise the concept of beats. Read through your book and then try this question.

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
