A star ship moving toward Earth with a speed of 0.78 c launches a shuttlecraft in the forward direction. The shuttle, which has a proper length of 12.3 m, is only 6.27 m long as viewed from Earth. What is the speed of the shuttle relative to the star..
Two moles of a monatomic gas with an rms speed of 294 m/s are contained in a tank that has a volume of 0.12 m3. If each gas particle has a mass of 8.220 × 10–26 kg, what is the absolute pressure of the gas?
A transverse wave on a string is described by the following wave function. y = 0.105 sin [(?/12)x + 5?t] where x and y are in meters and t is in seconds. (a) Determine the transverse speed at t = 0.290 s for an element of the string located at x = 1...
Two balls of equal mass collide and travel off in different directions as shown. Assume the red (inicident) ball leaves at an angle of 60ofrom it's initial direction of motion and the green (originally stationary) ball leaves at an angle of 30o. (Not..
