The problem is solved . thank you

Thank you for the attention sir . unfortunately i am using my phone to type so i cannot write all the calculation . can you please write the Energy released out of a mass defect of 1u by using Kg first then MeV /C2 as the unit of mass ? That can solve my problem

So 1u = 931.5Mev/c2 = 1.67 10_27 kg . the thing is when i calculate E=mC2 with both units the calculations don't match . i can't understand why .

i still can't quite grasp why the 6 is not necessary sir . so l'ets say the event wasn't the one i stated and was instead the player get's a red ball a white ball a red ball and then an other white ball , the number of possible combinations for that is A(5,2)*A(3,2) , the thing is that only...

thank you sir , though i can't just let this one go .. i used two Arrangements not one and then multiplied them together . can you please kindly explain to me how can the first format encapsulate all the possibilities ? thank you .

6 is in the numerator and sorry that's not A(8,2) i meant to write A(8,4) it's the total number of possible arrangements 6 -> (r,w,w,r) (w,r,r,w) (r,r,w,w) (w,w,r,r) (r,w,r,w) (w,r,w,r)

I cannot write this properly on the forum so let A(n,p) stand for an arrangement my solution is (A(5,2)*A(3,2))/A(8,4) * 6 , though it gives incorrect results so it's incorrect .

< Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown >[/color] i am doubting my solution to this problem , therefore i hope someone assists me a bit . it's simple , there is a bucket that contains 5 red balls and 3 white balls , a player picks up 4...

i classified this as a medical question because i though it has something to do with the brain and addiction . sorry . though how can one change his habbits ? may i ask ? can you guide me to some books or online articles ?

yes , i missed the sign . and flipped the numbers by mistake .

i am not asking for a diagnosis or anything , but it it impossible for one to change his bad simple habbits . for example if someone is used in eating like a savage and he does not chew his food , can this person become normal ? and if someone is not organised at all , can this person become an...

thank you sir :)

i have two unitary vectors in space U and V , U and V are perpendicular . W is a vector that verifies W ^ V = U - W . the following resolution is incorrect , i wan't to understand why : we use (o,U,V,(U^V)) . components of U (1,0,0) , V(0,1,0) , W(a,b,c) where a , b and c are real...

Hello . first of all , this is not a joke , this is a very serious situation and the only reason i am not seeing a doctor for this is the fact that i am afraid of being laughed at . my main problem is that i eat too much bread with meals , if dinner is macaroni for example .. i eat a large...

thank you very much sir , that helps a lot .
