The speed of light in some other universe is 30 m/s. You want to cover a distance of 100 m in 10 s (as measured on your watch) at a constant speed. a. How fast should you run? b. How long did it take you to cover that distance according to an observer at rest with respect to the track? (Carry four sig figs throughout the calculation).
Which of these statements are true? The speed of light is approximately 299,792,458 m/s and is...
Which of these statements are true? The speed of light is approximately 299,792,458 m/s and is uncertain to about 1 m/s The speed of light is the same seen by any observer anywhere in the universe If you are driving along at 100 km/hr, the light leaving your headlights is moving away from your car at 100 km/hr (0.0277 km/s) plus the speed of light, The speed of light is exactly 299,792,458 m/s

Imagine an alternate universe where the value of the Planck constant is 6.62607e^6 J *s . In that universe, which of the following objects would require quantum mechanics to describe, that is, would show both particle and wave properties? Which objects would act like everyday objects, and be adequately described by classical mechanics? object quantum or classical? A car with a mass of 1300. kg, 4.2 m long, moving at 93.0 km/h. classical or quantum? A virus with a mass...

The speed of light, by the u symbol c, has a value, to two significant figures, of 3.0 x 108 m/s. (a) How long does it take for light to travel from the Sun to Earth, a distance of 1.5 x 10!1 m? (b) How Jong does it take light to travel from the moon to Earth, a distance of 3.8 x 108 m? 1.0 In free light travels in a straight line at constant speed, c g along a...

9.1 Lorentz Contraction Objects traveling at relativistic speeds will appear to a stationary observer as shorter, as- suming that it is parallel to the direction of its motion. Using the equation for Lorentz contraction, find the following, where c is the speed of light: a) A spaceship is traveling with a velocity 0.8c. If it is 200m long in its rest frame (when the object is not moving), how long do you observe it to be? Assume that you can...
