Thanks for your response, I appreciate it. I think I will try both the general and physics GREs since, like you said, it's possible that I surprise myself with my score. Neither of the medical physics professors at my university appear to be doing much research with undergrads yet, would I...

Hey everyone! I'm currently an undergraduate student double majoring in Mathematics and Biomedical Physics at a CSU. Lately I've been getting a lot of negative prospects on potential graduate school options because of the fact that I apparently am set up for failure for attending a CSU (based on...

Thanks for your response. So, if I wanted to have a graph represent ##0 \leq x \leq 2##, would I essentially combine the translated graphs for ## t = 0, t = 1,## and ## t = 2##? Or would there be an emerging trend/'pattern' between values for ##t## that I would graph?

Homework Statement Graph snapshots of the solution in the x-u plane for various times t if \begin{align*} f(x) = \begin{cases} & 3, \text{if } -4 \leq x \leq 0 \\ & 2, \text{if } 4 \leq x \leq 8 \\ & 0, \text{otherwise} \end{cases} \end{align*} Homework Equations Assuming that c=1 and g(x)...

I don't really understand operator overloading at all but this is my attempt that led to an error class FamilyVacation result{ public: void result(int peopleCount, numPeople); private: }; void FamilyVacation FamilyVacation::result(int peopleCount, int numPeople){ peopleCount =...

Thank you! How would I copy numPeople? Anytime I try incorporating 'numPeople' into my solution, I get an error saying that numPeople isn't declared or that it could not be converted.

Hi, I'm having difficulty with this program in a textbook. The instructions are as follows: Overload the + operator as indicated. Sample output for the given program: First vacation: Days: 7, People: 3 Second vacation: Days: 12, People: 3 This is the code that follows #include <iostream>...

Ahhh I forgot to divide by 3. I checked the variables and the units should come out to N/C if I am working on the electric field of the sphere at (4m, 1.2m). Are you referencing the point (2m, 3m) as being outside of the sphere?

Here is a picture from my textbook that would probably illustrate what the differences between r and R are better than I could by explaining it. I used the equation of the electric field when r is less than or equal to R and set Q = ρV. Since the volume of a sphere is 4πr3, I substituted all of...

I have an attempted equation (excluding values) for the electric field of the sphere toward the end of my original post, Esphere = k*ρ*4π*r4/R3 r[hat] I don't know how to do the full calculation at point (2m, 3m). but the above equation is my guess of what to use to find the electric field of...

So would that mean that I only use the fact that ##\hat{r} = - \hat{i} + \hat{j}##? Also, if my equation for the electric field of the sphere is correct, would I plug in r = 3.606m and R = 1.2m?

So I got that the magnitude of the vector is approximately 3.606m at an approximate angle of 56.309°. ##\vec{r} = -3.606 \cos(56.309) \hat{i} + 3.606 \sin(56.309) \hat{j}## Thus ##\hat{r} = -0.5547 \hat{i} + 0.83205 \hat{j}##. Would I use that ##\hat{r}## for the equation of the sphere's...

The x and y components would be the radius (which is the hypotenuse, if I'm not mistaken) times cos θ and sin θ respectively. And the unit vector of a given vector is the x and y components of that vector divided by the magnitude of the vector itself.

Do you know why your instructor docked you points on your quiz? Here's an alternative route to getting started that's based on what you already have: For some x ∈ A ⊆ B, then x ∈ A and x ∈ B. Similarly, for some y ∈ C ⊆ D, then y ∈ C and y ∈ D. Cartesian products don't necessarily comprise of...

Homework Statement A nonconducting sphere 1.3 m in diameter with its center on the x axis at x = 4 m carries a uniform volume charge of density ρ = 4.8 µC/m3. Surrounding the sphere is a spherical shell with a diameter of 2.6 m and a uniform surface charge density σ = -1.2 µC/m2. Calculate the...
