1. A human's average life span is 80.0 years. How long in earth years would the average human live if they were travelling around the universe at 0.856c? (Please show steps for both). 2. Pinoccio's nose is normally 10.0 cm long, but he stole a cookie and has been lying about it. His nose grows by 10.0 cm for each lie he makes. You are in a spaceship moving at 0.9683c relative to Pinocchio and you measure his nose to be 0.800m long. How many times has he lied?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
