And how much did we have to write in description of alpha and gamma particle?
alpha - helium nucleus, positive charge , any other characteristic
beta - electron , negative charge, any other '''
gamma - transverse electromagnetic wave , speed of light , any other '''

great then :).

Why was the distance only a few centimeters from the source? So that alpha can be detected right since its range is less?

Q9's last part was 3.2 !!!!!

The resistors were in parallel and 2.5

So, 1/2.5 + 1/2.5 = 4/5, which reversed makes total resistance 1.25.

The current was 1.6 and power loss is equal to current squared multiplied into resistance

1.6x1.6x1.25 : 3.2W

No. One on top and one exactly under it.
just seeing that one on top and one across it doesnt make them in parallel.
you had to see the whole circuit.
i did this mistake first too but then i figured it was wrong.

Ok, help me here :

Q1) Mass, extension one.
Q2) Car's acceleration and stuff
Q3) House heating
Q4) angle of incidence and 32. something as angle of refraction one
Q5) wave motion and stuff
.
.
Q8) Wire and stuff
Q9) transformer wala
Q10) Gamme rays and Beta rays and stuff

What were question 6 and 7 about ?!?!?

lets ask others about this. cuz im not quite sure myself :unsure:
guys, are these 2 resistors connected in series or parallel ??
