E=mcdelta theta Power=Energy/Time Therfroe
Power*Time = Mass*c*delta theta.

Thank you, this was what I was looking for.
So in general we have;
scalar*scalar= scalar?
scalar*vector = vector
vector*vector = scalar.
What about work done though?
Work done = energy
So force * distance = vector * scalar? = vector
Could you also kindly tell me about how to prove mass...
I have done the example for momentum.
And I gather that scalar*vector=vector.
I know that mass and KE is scalar, velocity is vector.
Can someone show me proofs like for what I have said above.
Not just mass is scalar because it does not have direction etc.
Thank you.
After giving this some thought;
V = V0 e^(-t/RC) so as resistance increases then voltage decreases? Doesn't this contradict what you said - or am I totally wrong.
And what does DCR mean :/
Digital something resistance?
All good points.
alpha ~ 0.2mm of paper
beta ~ 1mm Pb/1-10 mm Al
gamma ~ 1-10cm of Pb/Several m of concrete
Measure initial count and discount it from the radiation present?
Could you not just use paper for example, alpha won't be able to penetrate it then say that, that radiation is...
