How does gravity help us explain the observations of patterns in space? Use your observations as
evidence to support your claim. Think about this: THERE
IS GRAVITY IN SPACE! When is the gravitational force the
strongest? What does it cause objects to do? How might
that help explain the patterns we've observed in space?

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.
