hell all please help me life or death situation

the starship enterprise wishes to fly to a distant galaxy 85 light years away. at what speed would it have to travel in order that the distance to the galaxy would only be 20 light years? :rolleyes:

a movving particle has a rent mass which is double in its kinetic energy. Find its speed and momentum :!)

you are sitting at rest on your brrom stick one day when a witch flies by at 0.25c the witch says her boomstick is 1.3 m long and yours is 1.5 m long what so you dtermine the length of these two brromsticks to be?

did you already post these problems in the homework section?
DON"T DOUBLE POST PLEASE...THIS IS A SELFISH BEHAVIOR... YOU ARE WASTING OUR TIME TO READ THE SAME POST AGAIN... IF YOU JUST WANT PEOPLE DO HW FOR YOU... HIRE A PRIVATE TUTOR... WE DON"T DO HW FOR PEOPLE...
 
A set of homework problems really isn't a life or death situation. But welcome to physics forum. If you read the FAQ's here, you'll see that there is a forum set aside for homework problems, and that showing your attempts to solve the problems is highly encouraged.

Thread 'Can this experiment break Lorentz symmetry?'

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Thread 'Relativator (Circular Slide-Rule): Simulated with Desmos - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
