No, you don't need the highest setting. Just stirring gently is enough, anything more won't help much. Salt dissolves very well in water. It dissolves so well, that an area of very salty water for...
What are the SI units of the wavefunction Ψ(x).I know that [Ψ(x)]^2 describes the probabilty of finding a quantum object at a certain quantum state but what about the wavefunction instead?
No, the answer can be seen by inspection in a few seconds, and it's not 2.8667. We don't just give answers to homework problems here, so I'll only make a few comments on the problem and your attem...
My optician counselled me I don't recommend a 1.74 index with a metal grooved frame, like the one you want from ic! Berlin, because the edge will be less resilient and be more susceptible to chi...
As we have set up communities here on the Codidact network we've been appointing temporary moderators. Ultimately, of course, we want each community to choose its own moderators; we've been doing ...
We need marketing more than moderators There is so little activity here, even one person can easily handle the rare moderation tasks. If you just need to put a name in a slot, then I'm willing to...
This site is not for five year olds. We are not kindergarten teachers. Asking a bunch of volunteers on the internet to explain physics to a five year old is a waste of time. Explanations at that...
Maxwell's first law in differential form states that $$ \triangledown \cdot E = \frac{\rho}{\epsilon_{o}} $$ . In case of 1d can we say that $$\rho = \lambda$$ where $$\lambda$$ is the linear char...
What examples of a system can be described by a system of ordinary differential equations?
The incremental inductance depends on the natural log of the l/d ratio. It also is reduced by the gap of the return conductor but is not affected by the dielectric around it. https://www.mantaro.c...
Can we use other laws of electromagnetism to calculate the inductance of a piece of wire just like we used Gauss's law to calculate the capacitance of the 2 seperated conductors? Yes. The inducta...
Gravitational waves can be derived from the non-linear Einstein field equations and since they are by definition waves they must obey the wave equation: $u_{tt}=c^{2}u_{xx}$ but in General Rela...
Lets say we have a mass connected to a spring.Assuming not any friction the ODE which describes the system is $m\frac{d^{2}x}{dt^{2}} = -kx$ We can set 2 Dirichlet boundary conditions $x(0)=0$ an...
Get 2 conductors and seperate them we can use Gauss's law to calculate the capacitance created by the seperation of the 2 conductors.Can we use other laws of electromagnetism to calculate the induc...
I'm trying to understand the uncertainty principle and its implications for particle measurement. From what I've read, it seems that the principle states that we cannot simultaneously know the exac...
If we have a LC high pass filter the transfer function H(s) becomes: $$ H(s) = \cfrac{sL}{sL + \cfrac{1}{sC}} $$ If we solve for s to find a pole of the transfer function we get: $$ s = j \cfrac...
Yes, that would the obvious interpretation of that equation in one dimension. Note also that in that case, the divergence also reduces to the ordinary derivative. In other words, in one dimension,...
$$\begin{alignat}{2} && \vec \nabla \cdot \vec D & = \rho_f \\ & \implies &\int_V \vec{\nabla} \cdot \vec D \mathrm d\tau & = \int_V \rho_f\ \mathrm d \tau \\ & \impl...
With time dilation a cosmonaut could travel forth in time, especially in light speed. But are there much lesser speeds which might be achievable by humans in the next 100 years which could also in...
Kinetic energy of any particle (who has mass) is $$T=\frac{1}{2} m\ddot{x}^2$$ OP had took potential as potential energy, that was wrong. $$U=-\int \vec F\cdot d\vec l $$ For the case, The forc...
No. A calendar or, more generally, a time measurement system, can be based on anything. While human calendars have (generally) been based on: Day = One cycle of the Earth's rotation Month = On...
We don't know the details of your setup, but most likely there was a partially reflective surface over the actual photoresistor. The photoresistor itself may also be partially reflective. A highe...
Let's start with displacement field equation $$\vec D = \epsilon_0 \vec E + \vec P$$ We know that $$-\vec \nabla \cdot \vec P = \rho_b$$ Here $\rho_b$ is surface charge density. $$\implies -\in...
The Euler-lagrangian equation gives the equations of motion that once solved give you a family of solutions that minimize the action. A unique solution is given by specifying boundary conditions....
I dont think anyone can make a universal calendar because time flows more slowly or more fast between different regions in the universe or it can even go backwards if you come close to a rotating b...
