Semi worked solutions for Light, Electric power and Sound

What those r the two elements..Hows tht parallel?? its just a wire twister rather going straight to the thing

[Whatlol]

i couldnt think of how to make it series )=

[mostafa1002]

no thats series, should be right i think

[Elnino_Gerrard]

IF i lose a mark for that !!! vCAA BETTER NOt ;P

[fady_22]

I KNOW OK i dint think of diagonal line thattime but its still series??

That's fine. You'll get the marks

i disagree with your answer to question 10 of sound! i believe its A =[

[Whatlol]

i disagree with your answer to question 10 of sound! i believe its A =[

It may well be, but i would think it is B since the 3000Hz produces a larger response than the 1000Hz

Hey, Whatlol, could you check the graph in option B for Sound Q10 and report if the 3000Hz sound had 1/3 the period of the 1000Hz sound?

The period of the sounds for graphs A and B are identical i just checked it then.
The 1000Hz sound on graphs A and B both take up 4 squares(for one period) The 3000Hz sounds on graphs A and B both take up 1 square for one period

Sucks to be me then because I chose A  :buck2:

it really depends on just what they implied by the sound intensities being the same at the microphone ,i personally feel this means that they are made the same that way their responses can be compared equally , for example if the 1000Hz sample was three times louder than the 3000hz sound when it enters the microphone, you may actually interpret that as them both producing the same response , since the microphone responds louder to the 3000hz than the 1000hz. So if they are both the same intensities when they enter the mic, then you will observe the differences.

Does it say that the frequency-response graph had to be used for the next question?

[cod101]

what did the Q6 graph actually look like? (in electricity)
i cant remember which one i put

Not directly, but i will write out the question for everyone.

"To test the frequency response of the microphone, a variable frequency sound source is used. The sound emits a pure tone of 1000Hz, followed by a pure tone of 3000Hz. The sound source is adjusted so that the two tones have the same sound intensity at the microphone. In the diagrams below, first a 1000Hz and then a 3000Hz signal are displayed on an oscilloscope.
Which display best shows what will be observed on the oscilloscope?"

Also at the top of the frequency response curve it states "The following information relates to Questions 9 and 10"

I personally feel that you must take into account the frequency response curve since what is displayed on the oscilloscope depends on the frequency response of the microphone itself.

Question six , i assume you mean for electric power.
Each graph shows you a the graph of flux versus time and over that it has the corresponding voltage. the answer (A) displays voltage as the negative rate of change of flux so it was basically a cosine curve (as the graph of flux was a sine curve)
