In a rocket test facility, aerospace engineers are testing a rocket's propulsion ability during a short test blast. The engineers measure a 150-kg mass flow of exhaust gas through the engine
at an average velocity of 200 m/s. What impulse could be delivered by this rocket?

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.

Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
