    How Long Does It Take for 80% of Carbon-14 to Decay in a Dead Animal?

    so i can just assume the Ro=100% although it is given No=80%?

    Understanding Nuclei Interactions: Strength of Strong and Weak Forces on Protons

    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)...

    How Long Does It Take for 80% of Carbon-14 to Decay in a Dead Animal?

    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...

    Meson vs. Baryon: Quark Interactions and Fermions/Bosons

    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?

    Meson Quark Model: Exploring q & S Combinations

    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

    Eigenfunction vs wave function

    is this right? ψ(x,t) = ψ1(x) + ψ2(x) wavefunction = eigenfunction1 + eigenfunction2

    Nucleon, Mass, and Atomic number

    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?

    Calculating Decay Constant Without Initial Value

    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

    Calculating Decay Constant Without Initial Value

    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?

    Calculating Decay Constant Without Initial 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?

    Calculating Decay Constant Without Initial Value

    It becomes A/5 = A exp -λ(2).. how can i get λ as the A is not given?

    Calculating Decay Constant Without Initial Value

    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.
