Hey, what did everyone think of this years Physics exam?

Was anyone else a little surprised by the ultrasound question, and do you think the grade boundaries will be high or low?

[Coveted Ul]

It was kind of hard. what do you think?

What did you put for the kinetic energy answer?

[Jeni68]

I put 4.25 x 10(the the -18).. i think

[Jpatch]

Ke energy was 1.6x10-19 x 150 so the answer is 2.4x10-17
Number going through a point was something like 4.5x10 17 so something like that

All in all I felt it was the hardest of all the EDEXCEl science exams but it still was fairly easy I thought.

The ultrasound was slightly weird. It wasn't hard it was just unusual . For example having to draw the beams of radiation was a bit pointless, it was practically impossible to not hit the spine.

[Coveted Ul]

It said name to factors of Ultrasound for total refraction to occur?

1. I wrote that it mustn't be bent too sharply
2. The angle of reflection needs to have a greater critical angle that angle of incidence

Would this be right?

[Coveted Ul]

For the KE one it was 140V (not 150) X 1.6x10-19

Could anyone post a mark scheme .
