    Two masses collide elastically...

    From the general expression for the total kinetic energy before the collision, I tried to derive m2, but I couldn't: Ec = 1/2 m1 v1^2 + 1/2 m2 v2^2 I can't extrapolate m2

    Two masses collide elastically...

    A body of mass m1 = 2 kg with a velocity v1 = 12 m/s collides elastically with a second body initially at rest. The first body continues to move in the same direction as the initial one but with a velocity equal to one-quarter of its initial velocity. Find the mass of the second body in kg. Thanks

    High School Question About Collapsing Supernova

    The inner part of the core, about 0.4 to 0.6 M⊙, is in sonic contact and collapses homologously, while the outer core collapses supersonically. Hi Could you explain the meaning of this sentence to me as simply as possible?

    High School Can anyone deeply understand relativity?

    Sorry, but Einstein was an engineer—how did he know all that math? Was he self-taught? In fact, he did work with a mathematician. So, did he theorize the imaginary part? Apologies to Einstein if I'm mistaken.

    High School What does "iron peak" mean in the collapse of a critical mass iron core?

    Is the binding energy per nucleon clearly equal to the energy required to extract a nucleon?

    High School What does "iron peak" mean in the collapse of a critical mass iron core?

    The collapse of the critical-mass iron core accelerates rapidly. This runaway is driven principally by photodissociation of iron-peak nuclei, Fe(γ, α), and by electron captures What does "iron peak" mean?

    High School Chandrasekhar mass is a function of electron fraction and core entropy?

    Hi everyone, Is it possible to explain in simple terms why the Chandrasekhar mass is generally a function of electron fraction and core entropy ?

    High School Supernova step of core collapse

    Here is the link: https://www.physics.rutgers.edu/analyze/wiki/cc_supernovae.html I noticed you used the term electron gas. Doing an internet search, I summarized it like this: Electron gas refers to a theoretical model in which electrons are considered as a gas of free or interacting particles...

    High School Supernova step of core collapse

    I read mass nears the Chandrasekhar mass limit (), the atoms become relativistic What does it mean that atoms become "relativistic"? That the motion due to thermal energy causes atoms to have speeds close to that of light; clearly, they cannot match that of light. What are the consequences of...

    Hi. I'm not a student, I'm an Italian astronomy enthusiast, and an older one at that. I enjoy disseminating knowledge, but obviously keeping in mind my skills.
