Answer:De acuerdo con la ley de inducción electromagnética de Faraday, la tasa de cambio del flujo magnético vinculado con la bobina es directamente proporcional a la fem inducida en la bobina.
e = - d∅ / dt
Entonces, si el cambio de flujo es mayor, la fem inducida es mayor.
¡espero haber ayudado a tener un buen día! :)
Explanation:
According to the Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is directly proportional to the induced emf in the coil.
e = - d∅ / dt
So, if the flux change is more the induced emf is more.
i hope i helped have a good day! :)
Answer:
Frequency = 658 Hz
Explanation:
The third harmonics of A is,
The second harmonics of E is,
The difference in the two frequencies is,
delta_f = 1320 Hz - 1318 Hz = 2 Hz
The beat frequency between the third harmonic of A and the second harmonic of E is,
delta_f = 
We have calculate the frequency of the E string when she hears four beats per second, then
delat_f = 4 Hz
Hope this helps!

20mph/3600 seconds/hour= .00555 MPS
.0055 miles per second
40 seconds to complete the change
