A home fragment found in a cave believed to have been inhabited byearly humans
contains 0.21 times as much14C as an equal amount of carbon in theatmosphere when the
organism containing the bone died. Find the approximate age of thefragment. Half life of 14C is 5730 Years.
Q # 2
Compare to a particles with the same energy, Ã particles that canmuch more easily
penetrate through matter. Why is this?
Q # 3
In what ways do photons resemble other particles such as electrons?In what ways do
they differ? Do photons have mass? Do they have electric charge?Can they be
accelerated? What mechanical properties they have?
