Edexcel A Level Physics Paper 3: 9PH0 03 - 16 June 2022 [Exam Chat]

For the one with the projectile and the box i got the projectile's velocity as something like 88m/s and the energy lost as around 250J

Can someone tell me if the half life question (32 days one) was enough time? I didn't get it as enough time after dividing by 2^4. And then calculating pressure using ideal gas equation. Highly likely that I got part of it wrong.

I don’t remember any of the calculations but I remember that 32 days was enough time since I worked out the number of particles with the gas equation and then used that number along with the number they gave us to work out the time for the initial number of nuclei to reach the final number of nuclei and it was less than 32 days

I got 124.7 m/s for the velocity and 491J.
I remember projectile was 0.065 Kg, block was 2.4 kg, and it went up 55 cm = 0.55m after collision.
I set mgh = 1/2 mv^2, then used mv projectile = mv projectile-block system.

Yeah I think you had to take away the nuclei after 32 days from the initial nuclei to just get the number of xenon nuclei, which got just over 1x10^5 for me

exactly what I did

Think question 2 was on terminal velocity I think

what was the very last question on the paper asking for ? I’m just really paranoid that I missed out a page/ part of question 13

Hey guys, what was the last question on the paper? I’m just really paranoid that I missed out a page

It was a question on mass per unit length for 6 marks

Did you all get the mass per unit as out of range? I got the min acceptable value as 2.15 something and the actuall mass per unit was 2.14 I think
