AI Thread Summary
The discussion revolves around the calculation of time based on an atom's movement, specifically when it hits a wall twice, resulting in a total distance of 2d along the x direction. The equation delta t = 2d/vx is presented to explain this relationship, leading to a query about whether vx can be derived as vx = 2d/delta t. The participants clarify that the formula for time is indeed time = distance/speed, confirming that the calculations are correct. The conclusion emphasizes that understanding the manipulation of these equations is straightforward once the relationships are clear. Overall, the discussion focuses on clarifying the mathematical relationships involved in the atom's movement.

I'm reading an explanation that involves the atom hitting the wall twice so the distance the atom traveled is 2d along the x direction in time delta t. Then the paragraph concludes that delta t = 2d/vx
So I assumed that it was because vx = 2d/delta t. Is that it? Or is there something that I'm missing? Thanks!

time=distance/speed
t=2d/vx

That's all there is to it.
 

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
