Physics P22, How was it!

[Albert Einstein]

Hehe guys, what did u put of the radiation, Gamma or alpha ?? last part of the last question

Hehe guys, what did u put of the radiation, Gamma or alpha ?? last part of the last question

gamma

 

[alcoholic 111]

hey guys what will be the threshold. Should it be 40 or 40-45?

37 - 38 I guess . It would be Low paper was tricky & a bit tough compared to previous past papers.

 

[alcoholic 111]

what were the forces acting on the spring while it was just released? weight and upwards tension ?

The question was that what was ONE force acting when the mass is released from the below point and it was TENSION

Hehe guys, what did u put of the radiation, Gamma or alpha ?? last part of the last question

Gamma Radiations

hey guys what will be the threshold. Should it be 40 or 40-45?

well, i had a talk with my teacher and he said he would be around 30-35 max. as most of the candidates were reappearing and plus its oct/nov.

What did you guys get for the change in momentum? And the one below it which was something about average force? Was it .065(5.2+3.7)
And then
F= .o65(8.5)/7.2ms

i think i did the same.

yep

 

[khan0000]

yep

5marks???

 

[shane123]

No it was not Alpha nor Gamma it was Beta for sure

 

[shane123]

Gamma Radiations

Their were forces asked not one force, please read the questions properly!

 

[geek101]

No it was not Alpha nor Gamma it was Beta for sure

there was no beta or alpha molecules in the equation..and gamma radiation is in the form of energy only...so it was deff gamma.

 

[emkay]

ahaha, i find it cute how we all are arguing on the answers

 

[Khalifa]

Its not alpha because alpha is helium nucleus while the eq showed helium atom only, with no charge. Dont know any logic behind how it could be beta.And yes, i remember clearly it said forces.

 

[Silent Hunter]

.And yes, i remember clearly it said forces.

so what did ya write? tension of spring upwards and the weight ?

 

[cHeStEr]

Question1 graph ?

I made this not sure

Me too mate .. well it looked similar yeah it must be this.

 

[dadufahad]

which part is this.. is this the 1 for showing that the velocity is approximately equal to 7?

no its the one with the cyclist..

 

[babycry]

no its the one with the cyclist..

which number and part was that?
