I cant really find any wavelengths to compare my calculated wavelengths to, just pictures of spectra, you cant make a positive id on that.
I have a blue/violet 1st order to the right of center, wave length=348.99, and to the left of center=523.359.
Looking at this...
Using data collected from a spectrometer, with a diffraction grating of 100 lines/mm, I have collected a set of data. From this I have calculated wavelengths for the 1st and 2nd order lines of the three brightest visible colors, which were Blue/Violet, Green, and Orange.
To complete my lab...
Im working to prove that an interior point on a chord is also interior to the circle containing the chord. Ive got the entire proof almost finished and laid out, however im stuck on one part. My proof would be complete if I could show this:
Given an isoceles triangle, in absolute geometry...
Honestly, Im not even sure exactly what radiated power means. Why is the 18.4mW not the radiated power of the light bulb?
I thought electrical energy was essentially work, which is a product of power and time, so how could radiated power be anything except 18.4mW? Are they referring to...
I know that the electric field lines between two oppositely charged points are symmetric, but I cant seem tof ind any refrence as to when this symmetry breaks down.
I want to say that electric field lines do not maintain symmetry if the two charges are not equal but opposite, e.g. a -4 and +4...
A) By definition linear charge density is Q/L. So for the inner conductor with 2λ I want to say it is 2Q/infinity but this cannot be right. Im sure using Guass's law produces a correct answer but I cannot see anyway to relate it to λ or length of the conductors for that matter
Well you would have
but how could you find the final charge without using a voltage?
Ive tried so many different ways using the formula for series capacitors and Q=CV and Ive had no luck solving this problem.
There must be some rule (or trick) Im missing involving combing C12 and C13 that im completely missing. Can anyone offer any insight into solving this problem?
Given this problem and its solution:
I think the given solution is wrong. The equivalent impedence is R + jwL || 1/jwC, right?
When I work out jwL || 1/jwC, I get ((jwL) * (1/jwC))/ (jwL + 1/jwC) = jwL / (j(w^2)CL + 1)...
Generally Im confused about the use of sin and cos in physics problems.
The torque about the beam's attachment to the wall is:
T * 8 * sin(53)
Where T is the tension of the wire.
Why is sin the choice and not cos...
For #2, here is the full question:
As for the first problem, their cycles are out of phase (5pi/3)/2pi = .83333, right? so if the points are 30cm apart, the wavelength is .8333 *30cm?
1) A transverse wave of frequency 25 Hz propa-
gates down a string. Two points 30 cm apart
are out of phase by (5*pi)/3
What is the wave length of the wave? An-
swer in units of cm.
Im kinda lost here, Im unsure how wave length will relate to the given info. Im sure the phase is part of...
Usually I can pick up most concepts pretty quickly, but EE just makes me feel dumb.
Ive managed to grasp most concepts we have covered this semester, except one, diodes. I really dont understand how to determine forward or reverse bias. For example...
For a 3kg object, displacement is given by 6i+3j-4k with a constant force F=2N i + -1N J + 7N k.
Ive found the total work, but the next question is ' Find the component of F in the direction of this displacement. Answer in units of N. '
Im really confused as to what is even...
ugh, nothing im doing is coming out right for this. for p1 and p2 im putting in h times g times 1000, filling in ½qv1 with 1/2 times 1000 times v1, and qgh with 1000 times 9,8 times height on tank.
this is just not coming out right at all
P1 + qgh1 + ½qv1 = P2 + qgh2 + 1/2qv2
im just confused on how to use it relating to this problem. p1 and p2 are the initial pressures on the holes, i think, so p1 = 1000 times 9.8 times 34 and p2= 1000 times 9.8 times 60
but then you plug these in and solve for h, correct, where h would...
A styrofoam slab has a thickness of 12.6 cm
and a density of 470 kg/m 3 . What is the area
of the slab if it floats just awash (top of slab
is even with the water surface) in fresh water
when a 65.7 kg swimmer is aboard? Answer
in units of m 2 .
im trying to use pressure=density of...
A meter stick, suspended at one end by a 0.502m long light string, is set into oscillation. Determine the period of oscillation in seconds.
At first I thought this would be a rather simple problem, so I did T=2pi*sqrt(L/g) but apparently this is very wrong.
Then I tried w=sqrt(g/l)...
Im kinda lost on this problem. Shouldnt the Y motion be described as A*sin(wt)?
In there equation we are considering when x=0, so the kx term is removed, but where is this third term coming from, and then should Y motion just be...
A solid cylinder of mass M = 42 kg, radius R = 0.14 m and uniform density is pivoted on a frictional axle coaxial with its symmetry axis. A particle of mass m = 4.2 kg and initial velocity v0 = 17 m/s (perpendicular to the cylinder's axis) flies too close to the cylinder's edge, collides with...
