I have fixed this error, and the one pointed out by mfb, using f(5) remainder of 0 and f(-2) remainder of -560 but am still not getting f(5) = 0 when testing it afterward. I also keep getting fraction/decimal numbers, is that to be expected or should I be getting whole numbers? Perhaps I am...
Thank you for your help.
Ok so for the first equation (x-5) --> remainder is 0, so f(-5) = 0
and for the second equation (x+2) --> remainder of -560
Is that correct? I have tried following this and using the two equations to solve for the variables in each other but when I try to test it...
the polynomial f(x) = ax4 - 3x3- 63x2+ 152x - b
has one of its zeros at x = 5 and passes through the point (-2, -560)
Question: Use this info to find the values of a and b
I am prepping for a test and this one question is really stumping me, I wondered if anyone would be able to help. For all...
Homework Statement
A block on an inclined surface is connected to another block that is hanging over the top edge of the incline, (as shown in the attached diagram). The system is moving in such a way that block B (mass = 3.0kg) is moving downwards, as block A slides up the ramp. The...
The other thing I can think of is that this supports the theory of special relativity because it predicts that viewed from the lab frame (earth), the muon will travel farther because it will have the velocity of itself plus that of the earth, despite it appearing to the observer that they are...
What would be the appropriate sign/symbol to use? As I said I wasn't given equations to use in any previous problems, so this was just the closest equation I could find that made the most sense. For that matter is that even the correct equation to use? Also does a) satisfy the "according to...
Homework Statement
A muon has a lifetime of 2.20 x10-6 s when at rest, after which time it decays into other particles.
a) Ignore any effects of relativity discussed in this section. If the muon was moving at 0.99c, how far would it travel before decaying into other particles, according to...
Yes, but that is what I am confused about. Initially, I thought the brightness doesn't have an effect on frequency, which I know does have an effect on the energy of photons. Everything I have been able to find has said that increasing the brightness means increasing the intensity, which I...
Homework Statement
Use Max Planck’s quantum theory to explain the following behavior of photoelectrons.
a) Low-intensity light does not release any photoelectrons. What will happen if the light is made brighter? Explain your reasoning
b) Low-intensity light releases photoelectrons. What...
Homework Statement
Compare and contrast a 2.2 eV photon with a 2.2 eV electron in terms of wavelength (m).[/B]
Homework Equations
p = h/λ
λ = h/mv
The Attempt at a Solution
For photon:
p = h/λ
λ = h/p
λ = (6.63 x10-34) / (1.17 x10-27kgm/s)**
λ = 5.67 x10-7 m
**I have already...
Homework Statement
In a TV tube, an electric potential difference accelerates electrons from a rest position towards a screen. Just before striking the screen, the electrons have a wavelength of 1.0 x10-11m. Find the electric potential difference.[/B]
Homework Equations
λ = h/mv
Ek = qΔV

Would this be the correct derivation?
E2=p2c2+m2c4
E2=p2c2 because m = 0 for a photon
p2 = E2/c2
p = √E2 /c2
p = E /c
I just want to make sure I got it right. Thanks
