Acharge q = 2.00 μc is placed at the origin in a region where there is already a uniform electric field = (100 n/c) î. calculate the flux of the net electric field through a gaussian sphere of radius r = 10.0 cm centered at the origin. (ε0 = 8.85 × 10-12 c2/n ∙ m2)

Several students in the group made comments to the coach about the back pack. which student has the correct analysis of the forces and motion of the back pack?

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.
