### 1.39 and 1.23

For 1.39 in regard to test #2, will we be expected to use dimensional analysis and convert mph to meters per second?
And also in regard to the test, for 1.23, will we have to know how to convert eV to joules on our own?

also the masses of electrons, neutrons, and protons would be given if we needed them right?

Unusual unit conversions such as english system to metric units will likely be given on the cover sheet. The cover sheet will contain other important constants.

It will be on the cover sheet. Conversion from eV to J, certain constants, and masses of particles will be there.

For the tests I think we will be given any information about conversions that most of us wouldn't know since we are being tested on concepts and applications, not conversions such as those from eV to J.
