My computer is connected to the Net through wireless LAN network.
It(my computer) fails to connect to the Net at the beginning of each month,
after I restored my computer a few days backwards, the problem was solved.
But this time I can't solve by restoring, my computer can continually...
sorry, it should be 4.2E6 J
I found the question quite confusing also...
from the model ans and equation V = KQ/r
r = 4.8E-15 m, which is the sum of proton and silicon nucleus radii
but i don't know the reason behind...
How much voltage must be used to accerlerate a proton (radius 1.2E-15 m) so that it has sufficient energy to just penetrate a silicon nucleus? A silicon nucleus has a charge of +14e, and its radius is about 3.6E-15 m. Assume the potential is that for point charges.
I have a conceptual question about fluid...
we derive the equations about pressure in fluid by considering the mass above a particular point in fluid.
and for fluid at rest, the pressure above equals pressure from below.
how about on the perpendicular plane? is the pressure on the sides equal...
I just had a glance on the nanotech program in the Uni, maths subject just appears in year one, they won't focus too much on maths afterwards
that's y I am considering 'chem eng' and 'material sci and eng.', there is more maths in these programs...
but I am interested in nanotech field...
I am interested in physics, maths and a bit chemistry
but i am not sure which course I should choose.
I have thought about nanotechnology(BSc), but there isn't much maths in the course...
I want to do more maths during my undergrad course.
I wonder 'chem eng' or 'material sci & eng' is more...
