I think it's cause he's only got a ruler for the horizontal and not the vertical.I also found it easier, band 6 cut off will defininately be higher. What did u guys write for the reason that projectile motion experiment was invalid? I honestly had no clue what to write so I just said that you can’t measure the horizontal displacement coz the starting position is not from the ground and this would affect the result. Would I get any marks for that?
If I remember correctly, X was the first, short one and Y was the second, longer one, but anyway maybe it was gamma... but both tracks were straight like a standard alpha pathWhat did people do for Wilson's cloud chamber for Y? I put gamma, cause the tracks were not zig-zag
X was alpha because they produce short and thick tracks(hence why it was in bold)I found the mcq very hard- probably list 4+ marks lol.
For Q2Q, what was source X and Y?? I was gonna put alpha radiation for both but it specifically states that they are different types of radiation, so I put:
X as beta
- shorter half life
and Y as alpha
- longer half life
I have no idea if that's correct :/
