In order to cross the galaxy quickly, a spaceship leaves Earth traveling at 0.9999995 c . After 15 minutes a radio message is sent from Earth to the spacecraft. (a) In the Earth–galaxy frame of reference, how far from Earth is the spaceship when the message is sent? (b) How much time elapses on spaceship clocks between when the ship leaves Earth and when the message is sent? (c) How much time elapses on Earth clocks between when the message is sent and when it is received’ (d) If the spaceship replies instantly with another radio message, what total time elapses on Earth clocks between when the message is sent and when the reply is received?

Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous
lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will
never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H.
pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is
composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 x 103 rpm. If the speed
of the bacterium is 10.0 μm/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00
* 10² rad?

T1. Calculate what is the received frequency when the car drives away from the radar antenna at a speed v of a) 1 m/s ( = 3.6 km/h), b) 10 m/s ( = 36 km/h), c) 30 m /s ( = 108 km/h) . The radar transmission frequency f is 24.125 GHz = 24.125*10^9 Hz, about 24 GHz. Speed of light 2.998 *10^8 m/s.
