ok so without that it becomes F = K/r^3 V(r) = ∫ F(r)dr V(r) = K/2r^2 dr/dθ = r^2/L√[2u(E-L^2/2ur^2- K/2r^2)] distributing and moving L dθ=dr/r^2 1/√[2uE/L^2 - 1/r^2 - uK/L^2r^2]^-½ substituting 1/r for ω and dr/r^2 for dω dθ=dω1/√[2uE/L^2 - ω^2 - uKω^2/L^2]^-½ consolidating dθ=dω1/√[2uE/L^2 -...

I was trying to apply Newton's theorem of revolving orbits and I believe I just went completely off from where I should have been heading

Question: A body of mass m is moving in a repulsive inverse cubed force given by F = K/r^3 where K > 0 show the path r(θ) of the body given by 1/r = A cos[β(θ-θο)] Find the values of constants A and β in terms of E, L. Work done so far: we did a similar problem with inverse square so I am...

radians is what we were told to do for all of these problems

Homework Statement After a laser beam passes through two thin parallel slits, the first completely dark fringes occur at ±14.0∘ with the original direction of the beam, as viewed on a screen far from the slits. A)What is the ratio of the distance between the slits to the wavelength of the...

yeah I see it now so starting my from my mistake m=-s'/s=-s'/(f-s') = (-s'/f)-(s'/-s)' m = -s'/f+1 m = -s'/f+1 m-1=-s'/f fm+-f=-s' -fm+f=s' 1/s-1/fm+f=1/f 1/s=1/f+1/fm-f 1/s = 1/f + 1/fm -1/f s=(fm)^-1

step 1: s = (1/f-1/s')^-1 step 2: m=-s'/((1/f-1/s)^-1) m=-s'(1/f-1/s) m=-(s'/f-1) (f/s')m=1 f/s'=1/m f=s'/m s' = f(m) step 3: 1/s+1/fm=1/f 1/s=1/f-1/fm s=(f-fm)^-1

Homework Statement Now consider a diverging lens with focal length f=−15cm, producing an upright image that is 5/9 as tall as the object. What is the object distance? You will need to use the magnification equation to find a relationship between s and s′s′. Then substitute into the thin lens...

Homework Statement Find the angle ϕ between the filter's polarizing axis and the direction of polarization of light necessary to increase the ratio of the clouds' intensity to that of the blue sky so that it is three times the normal value. Express your answer in degrees to four significant...

Homework Statement A light ray in air strikes the right-angle prism shown in the figure (Figure 1) (∠B=28.0∘). This ray consists of two different wavelengths. When it emerges at face AB, it has been split into two different rays that diverge from each other by 8.50∘ . Find the index of...

A monatomic ideal gas that is initially at a pressure of 1.60×105Pa and with a volume of 8.50×10−2m3 is compressed adiabatically to a volume of 4.00×10−2m3 A) What is the final pressure? - 5.63E5 B) How much work is done by the gas during the compression? C) What is the ratio of the...

Figured it out thanks!, took a good minute though

the Diatomic gas worked, forgot about that tidbit. but for the Part B I don't fully understand what you mean because I have 2 unknown variables V_f and T_f which is why I am a little lost.

Homework Statement In an experiment to simulate conditions within an automobile engine, 0.155 mol of air at a temperature of 780K and a pressure of 3.20x106 Pa is contained in a cylinder of volume 310 cm3. Then 670 J of heat is transferred to the cylinder. A) If the volume of the cylinder...
