At a given location the airspeed is 22 m/s and the pressure gradient along the streamline is 105 N/m3. Estimate the airspeed at a point 0.5 m farther along the streamline. First write the equation for the pressure gradient along the streamline. If neglest gravity,

Answer

given,

Air speed, v = 20 m/s

Pressure gradient, = 105 N/m³

distance,dl = 0.5 m

density of air = 1.23 kg/m³

Airspeed at 0.5 m = ?

relation between pressure gradient and speed changed

neglecting the gravity

Speed of the air at 0.5 m

V = 20 - 2.13

V = 17.87 m/s

Hence, the speed of air is equal to V = 17.87 m/s

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
