Answer:
The separation between the first two minima on either side is 0.63 degrees.
Explanation:
A diffraction experiment consists on passing monochromatic light trough a small single slit, at some distance a light diffraction pattern is projected on a screen. The diffraction pattern consists on intercalated dark and bright fringes that are symmetric respect the center of the screen, the angular positions of the dark fringes θn can be find using the equation:
with a the width of the slit, n the number of the minimum and λ the wavelength of the incident light. We should find the position of the n=1 and n=2 minima above the central maximum because symmetry the angular positions of n=-1 and n=-2 that are the angular position of the minima below the central maximum, then:
for the first minimum
solving for θ1:
for the second minimum:
So, the angular separation between them is the rest:
Answer:
0.00325 moles/liter/second
Explanation:
The tangent line has a slope of (y2 -y1)/(x2 -x1) = (0.35-0.48)/(40-0) = -0.00325.
The rate of the reaction is about 0.00325 moles/liter/second.
_____
This is the rate of decrease of the concentration of A.
The given question is incomplete. The complete question is as follows.
A 6.70 −μC particle moves through a region of space where an electric field of magnitude 1500 N/C points in the positive x direction, and a magnetic field of magnitude 1.25 T points in the positive z direction.
A) If the net force acting on the particle is N in the positive x direction, find the components of the particle's velocity. Assume the particle's velocity is in the x-y plane.
Enter your answers numerically separated by commas.
Explanation:
The given data is as follows.
Q =
E = 1300 N/C in the +x direction
B = 1.02 T in the +z direction
and, in the +x direction
Also,
= qE - qvB
Now, we will calculate the value of v as follows.
v =
=
v = 458.507 m/s
Using the value for velocity, we need to know which direction it's going.
You know +x direction for E, +z direction for B and +x for .
Using the right hand rule where:
your right thumb goes toward the , then your index finger points to B (z direction) Then curl your middle, ring, and pink 90 angle. This shows where v is going which is -y direction.
Thus, we can conclude that = 0, -(458.507), 0.
