Both the strong and weak interactions are short range forces of approximately 1 fm.
Two protons are separated by this distance.
Which equation should i use for these two question?
i) The strength of the electrical and gravitational interactions that influence each of
these protons.
ii)...
Im having trouble answering this question.
How long it takes for 80% of the carbon-14 to decay in an animal after it has died.
Carbon decays rate 0.012% per year.
So, my understanding is,
-(R = 0.00012 yr-1, t=1 yr)
R=Ro exp (-λt)
0.00012=Ro exp(-λ(1)) ---- (1)
-No = 0.8...
Mesons are bosons, while the baryons are fermions.
My question is, meson is a type of hadron that made from the interaction of quark with gluon. Quark is fermion, not boson. so why mesons are boson?
1) What is mean by fermion with half integer spin and boson with integer spin
Is that fermion, 1/2,3/2...
boson, 1,2,3
2) Why meson don't have q = +1, S = -1 or q = -1, S = +1 in term of quark model
What is differences between the definition of..
Nucleon number, atomic number, and mass number.
Is there any differences as i knew that those three symbol is A. am I right?
Hi! i dint find the the X2 button just above the Reply box.
1)If given half life. how to get initial decay rate?
-the question is, the half life of Ga-67 is 78 hours. Calculate initial decay rate
Really helps. tq! another question
1)If given half life. how to get initial decay rate?
From half life, i can get the λ.
Ro = λNo. how to get No?
2)What is seven half life mean? Is it 7T1/2 = value?
tq!:smile:
Can i ask another question here? If it violate rules, I am sorry. If it given initial activity 10 mci, how to know the number of atom inside?
Radioactive sample activity is said decreases by factor 5 during 2-h interval. How to find the decay constant? If the given initial value is not given? I don't know how to calculate.
