there is one problem with the textbook which you failed to notice. The question in the exam said "... relationship between the intensity of black body radiation...", your textbook said "... on the photoelectric effect...". Your textbook and the question are two different things, planck is the correct answer.
These are the answers, don't argue, they're right. I'll explain each one as well.
1. A
Acceleration is constant (gravity), so it's not B or D, only the y speed is 0 at the top so it is not C so it is A.
2. D
That's all it can be, can't really explain that one.
3. B
Again, that's all it can be, you just have to know that one. But if you look at formulas F = mv2/r and F = GMm/d2 the little ms cancel out which is the mass of the space craft and that's basically how it works.
4. D
This question is kind of wierd, but the question says it fires a forward facing rocket. A forward facing rocket can only slow it down and force it to come in. I did some calculations and it doesn't come down enough to hit the earth, so it has to be D.
5. C
People have already proved that one. Don't be retarded and talk about how golf clubs disprove it because golf clubs don't hit at a constant velocity and when you can hit it at exactly the same velocity and at complementary angles then come back and tell me what happened. Golf balls are also effected by spin on the ball, anyway, it's C.
6. B
Wierd question, the earth's magnetic field is basically uniform on earth so rotating a wire in it would do nothing as there is no change in flux linkage. But assuming it works, the length does matter because it means more flux linkage, so more change in linkage, the speed matters because it is changing quicker, and the direction matters because it only produces a current if it is perpendicular to the wire.
7. D
Right hand palm rule, not much more to explain.
8. A or C, it's a bad question. At the instant you closed the switch, there would be a spike in current, because there was a change in flux linkage. But because it is DC it would drop off and there would be no current. However, the question says "...when the switch is closed...". Do they mean the instant the switch is closed, or while the switch is closed? If it is the second part it is A, if it is the first part it is C. Bad question.
9. C
Eddie currents will slow down the ring in Q. P is plastic and R isn't connected so no currents. Therefore C.
10. B
That's just the way transformers work. The currents will be produced on the thin strips thus reducing them from if C was used. For C the currents would be around the big fat top bit and all the bits of metal, so it is B.
11. B
The cathode rays push the paddle wheel showing that they are particles with mass and speed and momentum.
12. A
As I said above, it's talking about black body radiation, he was the one that came up with the theory and the curve that fit experimental data. Einstein did photoelectric effect and said that all light is quantised. Planck said energy at the atomic level was quantised.
13. A
Boron produces an excess of holes. The electrons from the valence band will jump into the dopant level producing holes. My textbook Jacaranda HSC Science has that picture as a p type which somewhere else in the book says a group 3 atom is substituted in place of a group 4, ie. Boron or Gallium, boron for this question so A.
14. B
102.8 Mhz = 102 800 000. That times plancks constant = 6.812x10-26
15. D
Right hand palm rule again. Current moving along with magnetic field means electrons will move to top of rod and although holes don't "move" electrons going one way means holes going the other way. So it is D.
