How to find the resistivity of a non-metal?
Give this one a try later!
need a larger area and a shorter length as resistance will be very large so
you need bigger values to get a measure-able resistivity
resistivity = RA/l
,What must you do before taking count rate from a source?
Give this one a try later!
Take count of background radiation
Subtract from count for specified time
Divide the count by that time to get count rate

, n -> p + e- + X
Find x
Draw out the table of lepton, baryon and charge
n -> p + e- + X
0->1 -1
1->1 0
0->0 1
To balance the equation x must have a charge of 0, a baryon number of 0
and a lepton number of -1. This is an uncharged anti-lepton and therefore
must be an antineutrino

If the angle of incidence is greater than the critical angle no light is
refracted out of the medium and all of the light is reflected back into the
medium. All light has been totally internally reflected
