If a proton is moving at very high speed, so that its kinetic energy is much greater than its rest energy (mc²), can it then decay via p →n + n+? 2. What would an “antiatom," made up of the antiparticles to the constituents of normal atoms, consist of? What might happen if antimatter, made of such antiatoms, came in contact with our normal world of matter?
- The first picture is some background information need help answering the first question about the escape velocity from the andromeda GalaxySuppose an alien race on a distant planet tries to send a message to us, with a laser (light). However, we were unaware that there is a stellar-mass black hole almost directly between us and them. How would this complicate our attempts to locate their position in the Galaxy? O Gravitational lensing would make the signal appear to be coming from a different location O The information carried by the laser (light) would be altered O It would not matter The black hole absorbs all of the lightThere are two new equa3ons we need to learn about in this assignment (so that we can usethem in class on Wednesday). No need to derive or prove them – just look up the twoequa3ons in the book and then use them as explained below. If there’s a symbol in theequa3on you’re not sure about, read that part of the book carefully to see what it means.A) Find and report the equa3on for the Electric field due to a long line of charge. The keypart of the book is in sec3on 21.5, example 21.10. Keep in mind that we’re interested inthe limit of a very long (infinitely long) charged wire, where the equa3on looks simpler.B) Use the equa3on from A) to calculate the electric field 2mm radially out from the centerof a long thin charged wire. Assume the wire has a uniform charge of 3nC per meterlength. Make sure you give both the magnitude and the direc3on of the E-field at thispoint, rela3ve to the wire.C) Next, find and report the equa3on for the Electric Field due to a large plate of charge(spread over…
