  1. Why do fusion and fission both release energy?

    Jan 30, 2019 · In general, both fusion and fission may either require or release energy. Purely classical model Nucleons are bound together with the strong (and some weak) nuclear force. The nuclear …

  2. What do the symbols - Physics Stack Exchange

    Apr 18, 2018 · Please have a look at this presentation on Young tableaux, I'm trying to understand the signs I mention there - what do the $\\otimes$ and $\\oplus$ symbols mean?

  3. particle physics - How do the strong and weak forces relate to nuclear ...

    Aug 10, 2021 · Fission and fusion are due to the strong and weak forces, but it is unclear to me which is responsible for which.

  4. What are the Eigenstates and Eigenvalues? [closed]

    Jun 10, 2019 · Since you are supposed to ask only one question per post, I will answer only your first question about eigenstates and eigenvalues. Consider a matrix acting on vectors by matrix-vector …

  5. When will the pringles can fall? - Physics Stack Exchange

    $$ \frac {mgw} {2h} < \mu mg $$ or simply $$ h > \frac {w} {2\mu} $$ And we can test it out quick. I've got an empty paper cup on my desk. I've also got some graph paper. I can measure the width of the …

  6. Loss in KE in terms of reduced mass and coefficient of restitution

    Jun 1, 2024 · Where: μ = mAmB mA+mB μ = m A m B m A + m B, the system's reduced mass e = −V ⃗ ⋅i^ U ⃗ ⋅i^ e = − V → ⋅ i ^ U → ⋅ i ^, the coefficient of restitution between the particles U ⃗ =uA→ −uB→ …

  7. Why won't this electromagnet home experiment work?

    Jul 30, 2022 · I'm trying one of the most basic physics home experiments: creating an electromagnet by wrapping electrically-conductive wire around a metal screw. My ingredients: a metal screw I don't …

  8. Why do electromagnetic waves oscillate? - Physics Stack Exchange

    The above pretty much sums up my question, but for completeness' sake, I'm also including below references to some related threads I found: This guy asked "Do photons oscillate?". The responses …

  9. Why does maximal entropy imply equilibrium? - Physics Stack Exchange

    From a purely thermodynamical point of view, why does that entropy have to be a maximum at equilibrium? Say there is equilibrium, i.e. no net heat flow, why can the entropy not be sitting at a non-

  10. Why is $\\mathbf{B}$ a pseudovector? - Physics Stack Exchange

    Aug 21, 2017 · I got the difference between polar vectors and axial vectors (pseudovectors). An example of pseudovector is B B. But why exactly the magnetic field is a pseudovector and its components …
