I have recently become interested with the return of Nuclear Engineering with the recent political climate change over our dependence on foreign energy resorces. I know that there is another thread which discusses the prospects of new plants in detail, however I wanted to look at the long range...
I have y = ln(2x^3 + e) / 2
and I need to find the range for the function.
So I proceed to find the inverse [ ( e^(2x) - e ) / 2 ] ^ (1/3) = y
my memory is a little sketchy but don't I need to put the domain boundary value for the original into the inverse to find the range (apparently not...
Hello,
I'm looking for the following data:
in pure U-235, what is the distribution of ranges of fission products (under thermal neutron irradiation). I know that the distances involved are rather small, but I'm looking for their range. This must have been established somewhere, by...

Hello
I am taking 1st year stats at university, and I have lab questions I am supposed to answer. I am VERY confused.
My data set is:
53, 33, 25, 63,26, 64, 32, 21, 45, 64, 38
I calculated the mean:42.182
the sample variance:272.147
The range:43
The percentile rank of the data value 45...
A motorcycle daredevil is attempting to jump across as many buses as possible. The takeoff ramp makes an angle of 18.0 degrees above the horizontal, and the landing ramp is identical to the takeoff ramp. The buses are parked side by side, and each bus is 2.74m wide. The cyclist leaves the ramp...

My question is, derive an equation to find the maximum range of a projectile that's not on level ground. I am lost and i did attempt this, by making a diagram and subbing in what i thought i would need to use, but i still have not come up with the answer. please help
When iron, cobalt and nickel are placed in weak fields they assume a large magnetic polarization. I was wondering if this weak field needs to be either diagmagnetic or paramagnetic field. My guess is that it is paramagnetic but not sure which paramagnets could be used.
'Weak field' is used...
We know if the Earth is considered flat the maximum range is obtained when the missile is launched at an angle of 45 degrees. But what if we take into account the curvature of the earth? what is the maximum arc-length of the range? :confused:
Thank you!

Q. A projectile is fired with an initial speed V_0 at an angle \beta to the horitontal. Show that it's range alnog a plane which it's self is inclined at an angle \alpha to the horitontal ( \beta > \alpha) is given by:
R = \frac{(2{V_0}^2 cos \beta sin(\beta - \alpha )}{g {cos}^2\alpha}...
Hi all. I'm stuck on a physics problem obviously...So the original problem basically is a golfer is trying to put a ball 1.0m long or short of the cup. From uphill it is more difficult than downhill-explain why. Assume that the ball decelerates constantly at 2.0m/s^2 going downhill, and...

Hello.
Covalent bonding molicules, right, are usually in lower quantum energy states. e.g. for a typical dihydrogen mol at air temp, the 2 electrons are often in the first or second lowest quantum state.
But, natch, the molicule can still exist with the electron at higher quantum states.
In...

I'm a little confused about the difference between the half range Fourier series and the full range Fourier series. What is the difference between the two in an odd function like f(x)=x and an even function like f(x)=x^2 ? Maybe an example to clear things up. Thank you.
Hi,
As we know, lasers have longitudinal modes, the separation between neighbouring modes (measured in frequency) is:
\Delta \nu = \frac{c}{2L}
and by using the fact that:
\frac{\Delta \nu}{\nu} = \frac{\Delta \lambda}{\lambda}
we obtain the separation between neightbouring modes...
im doing a lab tomorrow that i must plan soon. if we fire an elastic band, the length we stretch it will affect the range but how do i support my hypothesis that range is proportional to pull back length?
do i use hookes law assuming that pull back length is the same as extention?
any tips...

For my article about long range artillery I was trying to calculate the magnus effect.
I first neglected air friction (which is ridiculous because without air friciton there is no magnus effect). For the magnus effect of a cylinder I used the formula:

I was given the equation y=2(3^x)-1 and told to state the domain, range, x and y intercepts and asymptotes.
I graphed the eqn and got the x-intercept to =-0.63 and the y-intercept=1
the vertical asymptote is the same as x-intercept so =-0.63 and the horizontal asymptote always equals 0...

Hi, does anyone know how to figure out the kernal and range for this linear transformation from P3 into P3 : L(p(x)) = xp'(x)?
