Lorentz transformation (cf. probs. 1.6.19+21 in textbook) an observer standing on earth observes spaceship travel (a) two spaceships are heading in the same direction toward earth, one at vi-0.95c and the other one at v2-0.85c relative to earth. what is the speed of spaceship- 1 as seen from the captain in spaceship-2? (b) two other spaceships are heading toward earth from opposite directions, at speeds of vz-0.8c and va-0.9c relative to earth. what is the speed of spaceship- 4 as seen from the captain in spaceship-3? (c) if spaceship-1 is 0.3ly (1 ly-1 lightyear, the distance light travels in one year) away from earth, how much older (in seconds) will be: (i) the observer, and (ii) the captain, once the spaceship has landed on earth?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
