A lot of students tremble with fear when they hear the word “physics” but still more students are seized by fear when they hear the word combination “atomic physics”! They study day and night but still get no results. Don’t give up! We are here to provide you with a special assistance for your atomic physics problems! You don’t have to be daunted by atomic physics any more as we have created a special system for only one purpose – to consider every single atomic physics question of every single student and provide them with the atomic physics answers in the shortest time!
A 100 g sample of a radioactive isotope has a half life of 2 days. After 6 days how many grams of the original radioactive isotope are left?
The pitch was clocked at 100.9 mi/hr (45.0 m/s). Determine the impulse required to give a 0.145-kg baseball such a momentum.
The mass of a typical car is m=1000kg. so its weight on the Earth’s surface is mg=9800N. Suppose you have two containers, one with N electrons and another with N protons. These two containers are placed a distance 10m apart, and the electric force between them is equal to the weight of the car. Find N.

What do you think would happen to the universe that we know today if the charge of the electron becomes positive and the charge of the proton inside the nucleus becomes negative?
Tritium is an isotope of hydrogen that decays by emitting beta particles. It is used in
some luminous signs. The symbol for tritium is (3 1 H)
a. Determine the binding energy in units of MeV. Given the atomic mass of
tritium is 3.0160492 u
b. Describe three differences between an alpha particle and a beta particle.
How old is the bone if if it is presently contains 0.3125 g od C-14, but it was estimated to have originally contained 80.000 g of C-14. the half life of Carbon-14 is 5730 years.
