Answer:

3.82 Hertz

Explanation:

y = 2.5 Sin\left (3x-24t+\frac{\pi }{2}  \right )

This is the equation of a wave which varies sinusoidally.

The standard equation of a wave is given by

y = A Sin\left ( kx-\omega t+\phi  \right )

where, A be the amplitude of the wave, k be the wave number, x be the displacement of wave, ω be the angular frequency and t be the time taken, and Ф be the phase angle.

now compare the given equation by the standard equation, we get

k = 3

ω = 24

Ф = π / 2

So, the angular frequency = 24

The relation between the angular frequency and the frequency is given by

ω = 2 x π x f

24 = 2 x 3.14 x f

f = 3.82 Hertz

What is a rule for determining the mass number of an atom or ion?
soldi70 [24.7K]
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. ... The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
