When an electron and its antiparticle (positron) combine, they annihilate each other
and become energy in the form of gamma rays.
9. What conservation law prevents this from happening
with two electrons?
10. The positron has the same mass as the electron.
Calculate how many joules of energy are released
when they annihilate. [Show all work, including the
equation and substitution with units.]

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

not too sure thinking all accelerations are pointed down

both the fifth and fourteenth amendments of the united states contain a due process clause. while the fifth amendment describes a legal obligation of the federal government to not deprived of life, liberty or property without due process of law, the fourteenth amendment applies the same obligation to the states to guarantee that all of the states provide fair procedures as well.
