Suggest two reasons why b-particles from a radioactive source would be inappropriate
for this type of scattering experiment.

Which type of scattering experiment? What do you mean? lol

Which type of scattering experiment? What do you mean? lol

The results of the a-particle scattering experiment provided evidence for the existence and
small size of the nucleus.
The a-particles in this experiment originated from the decay of a radioactive nuclide.
Suggest two reasons why b-particles from a radioactive source would be inappropriate
for this type of scattering experiment.Yeah this is the question.Now solve. -___-

Q6 (c) (ii) explain this
shouldnt pd remain same in parallel and series arrangement across R2when R1 is zero

Q5bii) was a piece of a cake so here you go, Q2 needs a bit of thinking which I can't afford it. As I am doing comp
Hope it helps

Its oK .. But Why Negative Gradient?..
Why wont It come backk to Zero? Wont it be at rest?

Hello there, for Q5 b(ii), if you look at the wave from P to Q, youll see that its 1.5Lambda, in part a)i), you already found Lambda, so subsititute youll get Length of PQ= 1.5 x 0.8= 1.2 m

Check that momentum graph again, I think there is some error, I cant figure it out.. coz meh mind is outta control due to computing... And the accn graph is same as I plotted it

Graph needs a fresh mind, if you have it you can plot it Simple.

Because i've faced these before and practiced them .

Any Genius can help me here please !
I can't sleep without solving these 2 question they are paining in my head ! X) OOOOH GOOOD

Smart Question

I didnt give the link for this one .And by the way m.s REJECTS high speed sorry .
β-particles have a range of energies
β-particles deviated by (orbital) electrons
β-particle has (very) small mass
(any two sensible suggestions, 1 each, max 2) B2 [2]
Do not allow β-particles have negative charge or β-particles have high speed [2] marks
