Hi All can anyone explain to me how you get the answer to Q14 for the OCR Modelling physics paper (set 2) the 2nd practice paper they released. The question is:
The answer according to the markscheme is A. I can get B but cannot work out how they have A as the answer. Please help??
I agree with you, the answer should be B.
I got B as well. To get A, they used 1 year instead of 1 day for T. If you calculate . So that is the error.
Thank you both Matt for clarifying precisely why its wrong and Luke for also helping me feel confident I’m not just losing the plot! Cheers both
Good spot, Matt. I couldn’t figure out what they’d done.
