Q1. A spaceship is approaching a space station at a speed of 2.1 x 10^5 m/s. The space station has a beacon that emits green light with a frequency of 5.85 x 10^14 Hz. What is the frequency of the beacon observed on spaceship?
What is the change in this frequency?

Q2. A 1.0mL syringe has an inner diameter of 6.0mm , a needle inner diameter of 0.29 mm , and a plunger pad diameter (where you place your finger) of 1.2 cm . A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100mmHg. Suppose the liquid is an ideal fluid. What is the minimum force the nurse needs to apply to syringe?
