Hi everyone,
If I have a static cylinder on an inclined rough plane at an angle alpha supported by a chord under tension, which leaves the surface of the cylinder at a tangent upwards and parallel to the plane. Does the weight component trying to pull it downwards equal the sum of the friction...
You're absolutely right, I completely over-thought the problem. So,
t[SUB]1 = Time particle takes between the 2 discs = d/u = L/u
t[SUB]2 = Time taken for disc 2 to reach correct position = θ/ω
For a particle to pass through both notches & hit detector, t[SUB]1 must equal t[SUB]2
So,
L/u =...
Hi everyone,
Molecules move into a vacuum chamber from an oven at constant T. The molecules then pass through a slit. They reach two rotating discs before finally reaching a detector.
Show that a molecule that passes through the first slit will...
