Atomic and Nuclear Physics Answers

Radiocarbon dating is the methanol method allows science to estimate the age of an organism after they died. fairly consistent amount of radioactive seeds 14 remains in the animal life what does the sea 14° overtime see 12 by measuring the amount of these two and a dead organism compared to living on along with the knowledge of half-life of C4 is 5730 years.
Can you determine how long the organism died?

a boy is inside a bus moving at 5.0 m/s toward the east. He is walking at 1.0 m/s toward the front. What is the velocity of the boy as observed by (a) a passenger sitting inside the bus and (b) another passenger waiting for the bus at a nearby bus stop?

1. In a nuclear reaction, the mass of the reactant is 236.05 atomic units, and the mass of the product is 235.86 atomic units.

(1 atomic mass unit = 1.667 × 10^-27 kg).

Calculate the energy released in the process.

2. The isotope radium -226 has a half-life of 1600 years and suppose you had 1000 grams of radium -226

(i) How much would be left 4800 years?

(ii) Why would it be more of a problem to dispose radium-226 than an isotope of the same mass with a half-life of 10 years?

Each of the following nuclei emits a photon in a y transition between an excited state and the ground state. Given the energy of the photon, find the energy of the excited state and comment on the relationship between the nuclear recoil energy and the experimental uncertainty in the photon energy: (a) 320.08419 0.00042 keV in 51V; (b) 1475.786 f 0.005 keV in "'Cd; (c) 1274.545 &- 0.017 keV in 22Ne; (d) 3451.152 2 0.047 keV in 56Fe; (e) 884.54174 f 0.00074 keV in 19,1r.

If an x-ray beam is incident on a 3mm thick sample and 50% of the beam is transmitted what is the average absorption coefficient of the material ?

Find the average velocity of the equation
x=t²+2t+3 when t=0, t=5

What velocity would a 60 kg person need to move at in order to have the same momentum as a 600 nm photon? (to 2 s.f and in m s−1)

the discovery of the higgs particle was an important contribution to our understanding to particle physics. describe the standard model of subatomic particle.you should identify the fundamental particles and the composition of the particles we can observe
