Homework Statement
Need to energy dissipation by the drap force on a ball in free fall from height h and when it has reached terminal speed, assuming it happens before it hits thr ground. Drag force has magnitude bv^2, where b is drag coefficient and v is instantaneous speed of the ball...
Homework Statement
When a satellite is at the desired altitude over the equator or Jupiter its velocity has the correst direction but the speed is (a) slightly faster that the correct speed for a circular orbit of the radius and (b) is slighly slower than the correct speed for a circular orbit...
I posted on this tangent a little while ago but I've moved forward and was looking for some input.
I have two exponential equations each is described by a different variable (n and v respectively):
y=1.44E-24*exp(46.22n)+2.006E-8
y=2.88*exp(-2.4v)-3.009E-5
Since the end constants are so...
I just watched the latest episode of NUMB3RS which brought up a very interesting concept called Coherent States. From what I got from the show this concept has something to do with data which contains no outliers and no anomalies, therefore pointing to a perfect solution. In the show it was...
Hmm I will try your method Werg but like you say I am not sure it is what I am looking for.
I am also trying to make both individual functions into linear expressions by taking the natural log of both sides however I run into natrual log rules which keep this from succeeding. Any ideas in the...
How would one go about dividing two exponential functions.
Basically I have f(x)=k*g(x)
So to solve for k, k=f(x)/g(x)
How would one accomplish this when the functions are both within the format:
A*e^(Cx)+B
Thanks
hmm, well i thought i did that since if
charge density = Q/(4pi*L*R1^2)
and the volume is pi*L*r^2
then multiplying the two would give (Q*r^2)/(4*R1^2)
ok, now I take this Q(enc) and put it Gauss to obtain:
EA=(Q*r^2)/(4*R1^2*Eo)
but you said Q is not present?
In any case I continued from this...
Ok ok I'm starting to see it, so i would have
(permittivity of free space= Eo)
int(E) x dA = Q(enc)/Eo
EA= (r^2/R1^2)Q/Eo
then dividing both sides by the area would give E?
and if so would I need to use the left side of the equation divided by the area of the face of the cylinder plus the...
To state my current attempt:
for part (a) i know
p=Q/4*pi*permittivity of free space*R1^2*L
V(enclosed)=pi*r^2*L
so p*V(enclosed)= the ratio (r^2/R1^2)Q which is the total Q enclosed
A long solid nonconducting cylinder or radius R1 is uniformly charged with a charge density (p). It is surrounded by a concentric cylindrical tube or innder radius R2 and outer radius R3, it also has uniform charge density, p. Before I can go on i need to find the electric field as a function of...
Thats a really good point about second hand stores. Only thing I have access too is garage-style sales, there is a saddening dearth of second-hand dealers in my area so online is my main source of literature.
Thanks for the input, I see what you're saying about physics texts, makes sense. also found another possibility
