For question 3 the experiment has nothing to do with momentum ?
For question 18 decreasing secondary coils will reduce the output current and thus reduce degree of flicking.
Not too sure about 6 and 11.

Also as they produce light and makes the shadow it shows it has energy.

Question 18 is C, since power is somewhat conserved, a lower voltage in the secondary coil due to less turns of wires means that the current will be higher, resulting in greater deflection.

Q3: Yeah it is B, just confirmed
Q18, it's a galvanometer, so we want an increased current register, NOT an increeased voltage
Q6: idk either
Q11: By definition, it only experiences a force due to gravity,

Question 6 I'm unsure about, either B or D but can't be certain. I made a stupid mistake with the Lenz's law question -.-

Fizzy for question 19 wouldnt it be C as same gravity means its in the same orbit ?

I picked B as the theories of special relativity were used as an explanation long before we tested it...

Wouldn't the force due to gravity be different as they have different masses?

How is 19 B?

Forces would be different as force depends on mass. Surely the astronauts mass is not equal to the mass of the spacecraft!

if they experienced the same force, they would experience significantly different accelerations.

If that had said 'acceleration due to gravity..' then that would be true.

To me 19 came by process of elimination :\

it is not A (force due to gravity would still be significant as it is the force which is causing the orbit in the first place), not C as the force due to gravity depends on mass, not D as that implies that the accelerations would be different due to the different masses (takes Force as being constant), B is left over. As shit as the answer is, it is B.

lol ?

 

[InteGrand]

Re: HSC Physics - Exam Paper (download)

lol ?

That's acceleration. Force is proportional to mass.

 

[Fizzy_Cyst]

Re: HSC Physics - Exam Paper (download)

lol ?

That is acceleration, not force.

 

[Joshmosh2]

Re: HSC Physics - Exam Paper (download)

It states force due to gravity.

Re: HSC Physics - Exam Paper (download)

How about question 6?

As soon as I saw this question, I thought of Q19 from HSC 2007 -- Only a theory once it has been tested and evidence supports it
