The question is two different cells with the same electrolyte, but one cell has a copper annode and tin cathode while the other has a copper annode and a zinc cathode, which cell has a higher voltage and why?

Physics?

Going to move this to the physics forum as you'll get more responses there. Please let me know if it's for a different subject!

Hello and welcome to TSR.

The way TSR study forum works is that you tell us your thinking / calculations and then we point you in the right direction to help you arrive at the answer.

It would help if you posted the full question if the answer requires the actual numerical values of the pd's or if this is a purely qualitative question?

To help you, think about the period and groups for each of the electrodes and specifically their electron configurations and the redox 'potential' of those elements to lose or gain electrons to reach equilibrium.

You may need to refer to the Standard Hydrogen Electrode (SHE) tables for a quantitative answer.
