Question

Answer 1

Let me try my luck first.....

Answer 2

319Hz?

Answer 3

idk:(

Answer 4

Your beat frequency is just changed

Answer 5

but the steps are initially the same

Answer 6

from 2 to 1Hz???????

Answer 7

Yup

Answer 8

give me a hint please.

Answer 9

\[1 Hz = |f_2-f_1|\]

Answer 10

that's what i was using OMG!!!

Answer 11

Awwwwnnnn!!! :"(

Answer 12

lol

Answer 13

What did we get for frequency b

Answer 14

322 and 318?

Answer 15

both are viable

Answer 16

but i guess 322Hz seems legit to me.

Answer 17

I got it, I'll let you think about it for a bit

Answer 18

ok but the formula is right tho?????right??

Answer 19

We don't need a formula, all we have to observe is the frequencies dropping 1 Hz

Answer 20

from the original

Answer 21

We figured out the frequencies were 322 and 318

Answer 22

ok so in the initial case the freak was 322Hz and beat freak was 2Hz but then it droped to 1Hz

Answer 23

So we have 318 drops to 317 and 322 drops to 321, now if we have beat frequency being 1 Hz, we have the following \[320Hz-317Hz = 1 Hz\] or is it \[321 Hz - 320 Hz = 1 Hz\] which one can we eliminate

Answer 24

second one would be it.

Answer 25

Yes, you're right, so our original frequency then is 322 Hz, notice the question specifies, tuning fork B AND beat frequency dropped 1 Hz. We just had to read it carefully :)

Answer 26

ooooooooooh i got it.....

Answer 27

so in the first case we got 322 and 318 and the beat freak was 2Hz but then then the beat freak droped to 1 Hz

Answer 28

Yes, as well did the frequency of b

Answer 29

they both dropped by 1, it's a nice question

Answer 30

It checks if you understand the concept or not :P

Answer 31

initially we had 320Hz + 2 beat freak = 322
bt then it drooped by 1Hz

Answer 32

Yes, that's what we figured out from the previous question, we had two frequencies for b and we had to decipher which one was the original

Answer 33

so 321 - inital 320 = 1Hz

Answer 34

Frequency A was 320Hz, not B

Answer 35

We figured out frequency b in your previous problem to be 322, and 318

Answer 36

yah that's what i meant!!!

Answer 37

and it told us in this part that frequency b and the beat frequency both drop by 1 hz

Answer 38

ok do you get it now? :)

Answer 39

79.329% but yah i think i got it.

Answer 40

Ok :)

Answer 41

Thanks an...just one more :")

Answer 42

>.<

Answer 43

Ok haha

Answer 44

I'm sorry love but we have to go through this together.....!! :") LOL

Answer 45

i've done the whole question but i'm just stuck at the line part. can you teach me how to do the calculations at the very end...here is a demo.

Answer 46
