Semi worked solutions for Light, Electric power and Sound

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

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.

Yeah, then it has to be B.
Damn... I thought it was a separate question.

Did anyone get Lenz's law for Q9 in the first section? I actually wrote negative gradient, which is wrong >.<

It is being debated whether it is Lenz's or faraday's law so we will find out once VCAA releases solutions (if anyone even cares then)

Haha, wouldn't care less by then.

There's this thing called pdf. It doesn't stand for 'portable' for no reason.

well im so sorry i couldn't get a pdf for you, im not good with using that software.
