Beat frequency problem. Your ear simultaneously hears waves from different sources, so it can hear beats from the two speakers.

podryga [215]

Completed question:Suppose one speaker is driven at 570 Hz and the other at 554 Hz. What is the beat frequency in Hz? The average frequency in Hz?

Answer:

Beat frequency= 16Hz

Average frequency = 562Hz

Explanation:

Beat frequency f = f2-f1

Where f2 is frequency of source with higher frequency

f1 is frequency of source with lower frequency

f1= 554Hz, f2= 570Hz

beat frequency (f) = 570 -554

= 16Hz

Average frequency = $\frac{554+570}{2}$

= $\frac{1124}{2}\\ =562Hz$

With the use of equation V= IR you are able to solve this probelm

So V=IR
V= 1.2 × 40
V =48v
