Hi, I was reading the wiki article here on beta decay and energy release: https://en.wikipedia.org/wiki/Beta_decay#Energy_release
In obtaining a condition on the masses of the initial and final atoms we neglected the difference in electron binding energies of the two atoms. Does this mean we...
I tried using time dilation, but I got a very small fraction of the speed of light, so I must have done something wrong. If it's not too much trouble, could you give a quick outline of the solution? I think I've confused myself too much thinking about it.
Homework Statement
A spaceship travels from Earth to the vicinity of the star that is measured
by astronomers on Earth to be six light-years away. The spaceship
and its occupants have a total rest mass of 32 000 kg. Assume that the
spaceship travels at constant velocity. The time taken as...
Ok, so what is meant by the angle 'with respect to the inner product'? Is it one of those things you must just accept is true, as I am having trouble visualising what is going on. Thanks for your responses.
Hi all, I am having trouble understanding inner products. Specifically, using inner products to find the angle between two vectors. Our lecturer has given an example, as follows;
(u,v)= 4u1v1 + u1v2 + u2v1 + u2v2, where u=(1,0) v=(0,1)
(u,v)=|u|.|v|cosθ
1=(√4)cosθ
θ=∏/3
Surely the...
