Can someone please explain why
the k value (-slope) for 0.025M NaOH is lower than the rest? When,
based on the trend, it should have a higher value than the slope of
the higher NaOH concentrations. What are possible reasons, if there
is an error?

Can someone please explain to me, why the current affects the x ray image contrast and the density of the x ray image? Also then again why would does the voltage affect these contrast and density. Would they affect the x ray image in any other ways And also what specific factors would you use these for in medical imaging using x rays - e.g. mammography, imaging of the lungs, please don't just state what, but explain why as well?
