Hi, NumberNine. Yea from what I learned so far, the first step is always to generate uniform RVs first, then do some transformation to make it to follow the distribution that we want. So we use uniform RV because it is very simple? as opposed to pick exponential RV first? So it is just the way...

Hi all! I started learning about Monte Carlo Simulation. However, one thing that I don't quite get is that why for generating any random variable, we have to first generate a Uniform RV? What is the reason behind that?
Thanks!
Hi, Jay. So change in KE is the same as NET WORK. and the conservation of energy equation: W=change in KE+ change in PE that we often use is for W for non-conservative force like applied forces? Never realized this before. When I learned energy, I first learned change in KE equals to work, but...
Homework Statement
A skier is pulled up by a towrope up a frictionless ski slope that makes an angle of 12 degrees with the horizontal. The rope moves parallel to the slope with a constant speed of 1.0 m/s. The force of the rope does 900 J of work on the skier as the skier moves a distance of...
If 1 kilogram of solid X at -20C gains 40 kilojoules of energy, its temperature will be ____
1) -120 2) -80 3) -20 4) 80
Given: Specific heat of solid: 0.4, heat of fusion: 60, melting point:-20,
So I did: mL+40=0.4(T+20) --> 60+40=0.4(T+20), T=230. But no choice for that.
Then I...
1. E (with dielectric) = E (w/o dielectric) – Ei =E/k what is E then? Original Electric field? But I thought the original one was E without dielectric? Do these two both refer to the same electric field?
2. Whether it's "First the wave theory" or any questions relating to wave in high school...
btw, If a negative charge is near positive plate, then we have to do work in order to move it to the negative plate, right? so in this case, it's moving against electric field? what If a negative charge is near negative plate, then do we still need to do work in order to make it go to positive...
I actually found setting 1 easier because I don't get why you chose the potential in the middle of the plates, but I get it now why positive is always at high potential, and negative is at low potential.
But induction is not conduction, why B will be net positive? If B is positive orginally, it's still postive; if it's negative, it will still be negative.
I drew these pictures, so some letters came unclear, I will clarify them later in parentheses.
Chp9,46, the diagram represents two small charged spheres, A and B, 3 meters apart. Each sphere has a charge of +2.0*10^-6 coulomb. (The point in the middle is y)
If a positive charge is placed at...
your proof seems to work very well, but just few questions here. why Vp=Ed/2, but Vn=-Ed/2, (why Vn is negative sign?) and /2 here means in the middle of the plates?
