Hi guys, sorry if i didn't follow the template but its more of a quick query than proper laid out question, but it is part of my coursework...anyway here goes;
I'm having a bit of trouble with an m-file in matlab, i posted earlier but i appreciate that post was too vague for a response...
------Question------
a) Research the three finite difference approximations mentioned above (forward, backward and central). Use a spreadsheet to demonstrate each of these numerical methods for the function below.
y=x3 −x2 +0.5x
Investigate the derivative over the range x = [0,1], using...
A redshift survey has identified a galaxy cluster for which it infers a di stance of 520 Mpc. At what redshift is this cluster observed to be? You may use H0 = 72 km s−1 Mpc−1
Now call me old fashioned but don't i need some kind of relativistic speed to calculate the redshift, i mean i have a...
Thanks for the reply phyzguy i was thinking i needed loads of extra info but now i realize the only bit of information about Po 210 that I could find online would be its half life as the activity and decay constant etc etc etc depend on how much of the stuff is left in this case 320g
Question
The α-emitter 210, 84 Po is used in a nuclear battery. The kinetic energy of the emitted alpha particles can be worked out from energy and momentum conservation. It is converted into electrical energy at 5.0% efficiency.
(a) Determine the initial power output (in W) of the battery...
Why does half a wave length and not a full wave length constitute the first harmonic?
v=\lambdaf
because a standing waves can be made with two half waves traveling in opposite directions?
well, i mean i took a guess that it takes that form, but is gamma squared or cubed?...anything that could change the proportionality...you know :)
cheers
basically what is the relationship between mass density at "zero" speed and mass density at speeds nearing the speed of light (0.98c,0.99c etc)
in the form M = \gamma Mo if possible
Thanks a lot guys!
