PLEASE I NEED HELP A forensic investigator notes that an 8g lead bullet melted completely upon impact with a doorframe. Assuming the bullet was fired at room temperature (~20 OC), what would be the minimum muzzle velocity of the gun (in other words, how fast was the bullet traveling)?

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.
