A hypothetical substance has a compressibility k = a /V and a volume expansivity
B = 2bT /V , where a and b are constants and V is the molar volume. Show that the
equation of state is:
V = bT2 - aP + constant
To be honest I'm not entirely sure what I'm actually supposed to be doing with...
A grating having 600 lines per mm is illuminated with sodium light of mean wavelength
589.3 nm. Determine the maximum order of diffraction that can be observed. By
differentiating the expression: d sin θ = m λ, calculate the angular separation in arc minutes
in second order for the two...
Ok, so I tried again and I got,
for v = 100m/s, D = 10N,
using D = bv^2, b=10/100^2 = 0.001
and then using v(t) = {sqrt(mg/b)... expotential stuff, which gave me an answer of 23m/s after 3 secs, but I don't know if that seems reasonable because as the velocity drops, so does the drag so how...
Homework Statement
A ball of mass 0.5 kg traveling horizontally through the air with speed v(t) experiences
a drag force DT (t) whose magnitude is given by:
DT (t ) = 0.01[v (t )] 2
The speed of the ball is found to reduce from 10 m/s to 8 m/s over a time interval t,
during which time...
