I have tried to write down the boundary conditions in this case and looked into them. As conditions i) and ii) were trivial, i looked into iii) and iv) for information that I could use. But all I got was that for the transmitted wave to have an angle, the reflective wave should also have an...

This was the equation that they showed me.
I thought P was for pressure, V for Volume, T for Temperature, R for Gas Constant, and n for the number of moles.
Was I correct for the initials?
Hello, I am trying to understand the maths/physics/chemistry behind this situation. Here is the scenario. I have 8 grams of pressurized N2O in a cylinder at 60 bar/ 900 psi. If the temperature stays constant (let's say 50-70°C, or at a temperature where the N2O can stay as pressurized as...

Since Fg = Gmm/r2and Coulomb's law being similar to that: Fe = kQq/r2,
and we also have E = kQ/r2 and g = Gm/r2 being alike,
I was wondering if there's anything that corresponds to the potential equation kQ/r. I converted it myself and figured that it's going to be Gm/r, and I'm not sure if a...
Hello everyone!
I'd like to know if it's possible to solve an equation with a modulus like this one :

Hello.
The curve y = x2 is a parabola that looks like this:

Hello everyone,
I need some help (or guidance).
I have an equation f(x) = A/(x2). I need to construct the equation g(f(x)) with following conditions:
- when f(x) -> 0 then g(f(x)) ->1;
- when f(x) -> Fmax then g(f(x))->0; (This is important: there is some fixed Fmax value at which g(f(x))...

So if i take the rules that a straight vertical line drawn through the function with more than one intersection implies it is not a function, to mean that the quadratic equation for a circle is not a function.
Furthermore, it also implies a cubic equation, such as x^3 can be a function, because...
I derived a relationship between frequency and tension of a string, accounting for tension's effect in the linear density of the string.
So in a nutshell, the equation is more complicated and is in the form of

How should power be calculated in a situation where distance and time are both given, as well as mass. At first, I was thinking of just using W=Fx (force as mass x 9.8) to solve for work, and then I would take the solution for work and put it into P=wt.
Does this make sense? That's my best...
