Consider the inelastic collision e^-+e^- \to e^-+e^-+e^-+e^+ in which an electron-positron pair is produced in a head-on collision between two electrons moving in opposite directions at the same speed. What is the speed of an electron with the threshol
Suppose a proton is moving at 0.95% of speed of light. Calculate the wavelength in meters of a photon that has the same momentum as this proton.
Laboratory scientists have created the electric and magnetic fields as shown in the figure below. These fields are also seen by scientists that zoom past in a rocket traveling in the x direction at 1.0 \times 10^6 \space m/s. Assume that B = 0.42 \space T
Explain this statement: Rest mass of the photon is zero.
The nearest star to our own Sun is Proxima Centauri, at 4.24 light-years. If a spaceship travels at 0.75 c, how much time is required for a one-way trip according to an Earth observer?
A rocket launched outward from Earth has a speed of 0.190 c relative to Earth. The rocket is directed toward an incoming meteor that may hit the planet. If the meteor moves with a speed of 0.260 c rel
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. Part A: At what constant velocity must a spacecraft travel from Earth, if it is to reach the star in 5.4 years, as measured by tra
When you approach a blinking source of light, the frequency of its blinking is seen to: a) decrease b) increase c) remain the same always. If you are traveling at close to the speed of light and shi
A spacecraft approaching the earth launches an exploration vehicle. After the launch, an observer on earth sees the spacecraft approaching at a speed of 0.74 c and the exploration vehicle approaching
In the theory of relativity, the mass of a particle with velocity v is m = m0/sqrt(1-v^2/c^2), where m0 is the mass of the particle at rest and c is the speed of light. What happens as v->c^-? A. m->m0 B. m-> infinity C. m-> 0 D. m-> -infinity.
