scientists collided atoms of small mass together, observed reaction products with twice the mass of original atoms, and described this result as fusion.
scientists bombarded atoms of large mass with neutrons, observed reaction products with slightly smaller mass, and described this result as fusion.

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 22Ā°c and leaves at 47Ā°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.
