11. A car is moving at a rapid pace. It is approaching a garage with doors at either end. The proper length of the car is longer than the garage. As the car travels through the garage, describe what the driver would observe. Describe what would be seen by a stationary observer inside the garage. [3 marks] 12. A beam of radioactive particles travels at a speed of 2.5 x 108 m/s. The half-life of the particles in the beam is measured to be 1.4us by an outside observer. Determine the half-life of those particles when they are at rest with respect to the observer. [2 marks] 13. Imaginary element Q has an atomic number of 129 and an atomic mass of 345. Complete the nuclear equation for element Q if it emits an alpha particle and daughter particle NQ. [3 marks]
