Can someone explain why these 2 answers are wrong?

The first picture is 3b. Kinetic energy is 2x10^-19

For #2, I think you got all the calculations right, but you might have gotten points off because of units. You needed to put meters after your calculation for the minimum delta x. But I'm not sure if that's just 1 point off or 2!
