i said D cause the charge of a alpha particle is 2e. What u said is for an electron

i said D cause the charge of a alpha particle is 2e. What u said is for an electron

Which question was that ??

 

[Ahmedlool]

q 38 the answer was an alpha particle has a speed of 1.5 something so the ans is d

 

[h4isms]

what did you guys get on the 'a battery is marked 9V question' and the one in which lamp was in parallel?

 

[Bba321]

For the 9 V one I marked A

 

[Ahmedlool]

It got it A since the speed of an alpha particle is 3*10 7

Its D since the speed of an alpha particle is withing that range the answer was 1.5*10 to the power of 7

 

[AhmedHesham]

what did you guys get on the 'a battery is marked 9V question' and the one in which lamp was in parallel?

I did it A too

 

[AhmedHesham]

What about the question of the two loudspeakers and asked which graph shows the correct intenisty ?? I made it C

 

[Ahmed Khattab]

Yea me too i got C

 

[h4isms]

the one about the polymer which type was it

 

[Ahmedlool]

i got B

the one about the polymer which type was it

 

[Ahmed Khattab]

?

 

[AhmedHesham]

Q39 asked about the stages to change from a particle to another one
I made it B which is 8 stages

 

[Ahmedlool]

yea thts right
