1 mole is 6.002e+23 molecules. 500 molecules have 8.3e-22 moles. I am not really sure what you meant after that. Volume = (liter)^2? Isn't Volume[m^3] = [1000* Liter]
I have the following program that moves a wave on a string with fixed ends. The program solves the wave equation given a initial condition wave. The initial condition is a triangle wave splitting into two pulses.
Here is the code written in Python:
from numpy import *
from matplotlib.pyplot...
Thank you for your reply. I read the article,but had problem understanding "the normal mode of oscillations". But how is it then possible to create a single pulse traveling along the string?
Yes, same initial conditions. But is it something more behind it than a symmetry argument? That is why I was asking about standing waves and superposition.
When we pluck a string and a triangle is formed. Why does this triangle form into two opposite moving pulses? If we have reflective edges the two pulses will reflect, invert and superposition into the same triangle wave on the under side of the string. Let's say we have no dampening.
I think...
I found vs by using eq (3):
$$ v_{p} = \sqrt{\gamma m_{s}} \approx 13061 m/s $$ then using (4)
$$ v_{s} = \frac{m_{p} v_{p}}{m_{s}}\approx 12 m/s $$
But vs is ≈ vrs, but still not vrs
But couldn't I use a different method with eq(1) and eq(2) to find vrs?
I believe it's the period of the sun around the sun- Jupiter center of mass system( a little outside the sun). Vrs is the radial velocity of the sun around this center of mass.
I only used SI - units (m/s, s, kg)
EDIT:
I also meant r = d (distance between sun and planet)
Yeah, I forgot r3Here is equation (1) and (2)written in LATEX
(1)
$$ P_{star} = \sqrt{ \frac{r^{3}4 \pi^{2} }{ \gamma m_{s} } } $$
(2)
$$ v_{rs} = \frac{m_{p}(2 \pi \gamma )^{ \frac{1}{3} } }{m_{s}^{ \frac{2}{3} }p^{...
Hello, I have an exercise here that I need help with.
The precision in measurements of radial velocities by the Doppler effect is currently 1 m/s. Can a Jupiter like planet orbiting a star similar to the Sun at a distance from the mother star equal to the Sun-Jupiter distance be detected? (Use...
Can you explain the difference? I saw this video and I couldn't explain why the balls with bigger R went faster in oil. But in air all balls fall with the same velocity??
